Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on July 9 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Wioletta Ruszel (University of Utrecht) Title: Local central limit theorem and potential kernel estimates for a class of symmetric heavy-tailed random variables. 09 JULY (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: In this talk we will discuss stable local limit theorems and potential kernel estimates. In particular we consider a class of heavy-tailed random variables on Z in the domain of attraction of an -stable random variable of index \alpha \in (0, 2) satisfying a certain expansion of their characteristic function expansion. Our results include sharp convergence rates for the local (stable) central limit theorem, a detailed expansion of the characteristic function of a long-range random walk with transition and detailed asymptotic estimates of the discrete potential kernel. This is joint work with Leandro Chiarini (UU) and Milton Jara (IMPA) and is based on arXiv.com/2101.01609. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

pst-doc in Statistics, University of Florence
by Monia Lupparelli 29 Jun '21

29 Jun '21

* Apologise for cross-posting * Dear Colleagues, I would like to inform you that a post-doc in Statistics is available in the Department of Statistics, Computer Science, Applications at the University of Florence, under the supervision of Prof. Monia Lupparelli and Prof. Francesco C. Stingo. Deadline for application: July 12th 2021 Starting date: November 1st 2021 Research topic: Bayesian model search for profile undirected graphical models The research project aims to develop a graphical modelling approach to study the effect that a risk factor may have on a set of random variables and on their joint dependence structure. This issue could be partially addressed by using chain graph or multiple graph models: the first method ignores how the dependence structure may vary under different profiles defined by the external factor, the second does not account for the effect of the factor on single variables. The research should develop a class of profile graphical models to fill the gap between the existent graphical approaches. As far as inference is concerned, model selection represents a crucial aspect since compatibility constraints for the model identifiability need to be considered. The idea is to implement Bayesian stochastic search approaches for the selection and inference of discrete profile graphs, both for moderate and high dimensional data. The proposed methodology will be applied to biomedical data. Details can be found at https://bandi.miur.it/bandi.php/public/fellowship/id_fellow/192962 <https://bandi.miur.it/bandi.php/public/fellowship/id_fellow/192962> and https://titulus.unifi.it/albo/viewer?view=files%2F004108400-UNFICLE-701729a… <https://titulus.unifi.it/albo/viewer?view=files/004108400-UNFICLE-701729a1-…> Best Regards, Monia Lupparelli ----------------------------------------- Monia Lupparelli, PhD Department of Statistics, Computer Science, Applications University of Florence Viale Morgagni 59, 50134 Florence, IT Phone +39 055 2751579

Annuncio: GNU TeXmacs versione 2.1
by Massimiliano Gubinelli 25 Jun '21

25 Jun '21

Cari colleghi, insieme ad altri ricercatori da molti anni sviluppiamo un editor di testi scientifici (e non) che si chiama TeXmacs (www.texmacs.org) e che permette di scrivere articoli, preparare presentazioni, etc.. rimpiazzando l'uso dei vari sistemi basati su TeX con un'interfaccia più sintetica e moderna. TeXmacs non è basato su TeX ma può esportare i documenti in vari formati, tra cui HTML, PDF o appunto (La)TeX. Il software è libero, parte del progetto GNU (per chi conosce questa iniziativa e i suoi scopi) e compatibile con Mac, Windows e i vari sistemi Linux. È un sistema che per molti di noi è diventato uno strumento di uso quotidiano, sia nella didattica (sopratutto in questo periodo di insegnamento a distanza) che nella ricerca e nella produzione di documentazione scientifica: articoli, tesi, libri. Da poco abbiamo rilasciato la versione 2.1 che rappresenta il consolidamento del nostro lavoro dell'ultimo decennio e all'occasione cerchiamo di fare un po' di pubblicità all'iniziativa per favorirne la diffusione. In particolare abbiamo prodotto un corto video di presentazione (~4 min) che riassume le caratteristiche salienti del sistema: https://www.youtube.com/watch?v=H46ON2FB30U In rete trovate anche varie risorse di informazione: un sito web dove scaricare il programma, un forum e delle liste di diffusione. Per maggiori dettagli faccio seguire il messaggio ufficiale in inglese. Sperando che questa iniziativa possa essere di interesse e utile, vi porgo cordiali saluti, Massimiliano Gubinelli -------------------------------------------------------------------- Dear colleague, We are happy to announce the release of GNU TeXmacs 2.1, a free scientific office suite that you may download from https://www.texmacs.org The core of the system is a what-you-see-is-what-you-get structured text editor with support for mathematical formulas. For a short overview, you may watch the following video (3 min 40): https://www.youtube.com/watch?v=H46ON2FB30U TeXmacs is unique in its ability to produce documents with the highest typographical quality using a user friendly interface. The software also comes with an integrated presentation tool, a picture editor, version control, a bibliography tool, interfaces to various mathematical computation systems, and much more... GNU TeXmacs is not based on TeX/LaTeX, but comes with high quality converters from and to LaTeX, as well as Html/MathML/MathJax. In order to get started with TeXmacs, we recommend that you watch one or more of our introductory videos: https://www.texmacs.org/tmweb/home/videos.en.html The software provides integrated documentation and a manual that can be downloaded from https://www.texmacs.org/tmweb/help/book.en.html A new book about TeXmacs is available here: https://www.scypress.com/book_info.html For further questions, don't hesitate to ask on one of our mailing lists or on the TeXmacs forum. With our best regards, The TeXmacs team

Dear colleagues, I am happy to forward you the following announcements of two seminars in Quantitative Finance organized by LTI@UniTO and Collegio Carlo Alberto: * Matthijs Breugem (CCA) on Tuesday, June 29th: "On the impact of Long Term Investors on Information Choice and Market Efficiency" * Carole Bernard (Grenoble Ecole de Management) on Thursday July 1st: "Option-implied dependence and correlation risk premium". Please find below the abstract and the zoom links. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/SNnQ5aISnSkDsUrrKkdJ5noQSxbj4pJWMq…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the following webinars <#> *June 29, 2021 | 12:00 - 13:00* *“On The Impact of Long Term Investors on Information Choice and Market Efficiency”* *Matthijs Breugem (Collegio Carlo Alberto)* <#> *Abstract* We analyze the impact of investor investment horizon on information acquisition and market efficiency in an REE economy with short-term and long-term investors. We find that the presence of long-term investors increases the willingness of short-term investors to acquire long-term information. Specifically, short-term investors care about long-term information to the extent that future prices—at which they liquidate their investments—reflect long-term payoffs. Long-term investors acquire long-term information and therefore increase the price-informativeness of future prices. Therefore, the larger the fraction of long-term investors, the more long-term payoffs are reflected into future prices, and the more long-term information is acquired by short-term investors. *Zoom Link:* *https://us02web.zoom.us/j/83290754621?pwd=Q3NoaWlIdXpnSkovdjlRTXE1OE5jdz09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/PA1lvCniowZZn-8vKUfINTd51_6qus8e1k…>* Meeting ID: 832 9075 4621 Passcode: 359187 <#> *July 1, 2021 | 12:00 - 13:00* *“Option-Implied Dependence and Correlation Risk Premium”* *Carole Bernard (Grenoble Ecole de Management)* <#> *Abstract* We propose a novel model-free approach to obtain the joint risk-neutral distribution among several assets that is consistent with market prices of options on these assets and their weighted index. In an empirical application, we use options on the S&P 500 index and its nine industry sectors. The results of our analysis reveal that the option-implied dependence for the nine sectors is highly nonnormal, asymmetric, and time-varying. We then study two conditional correlations: when the market moves down or up. The risk premium for the down correlation is strongly negative, while the opposite is true for the up correlation. These findings are consistent with the economic intuition that investors dislike the loss of diversification when markets fall, but they actually prefer high correlation when markets rally. *Zoom link: * *https://us02web.zoom.us/j/81288915014?pwd=YjEzZVpIcG9XV0dIQ0VIT3U1MlNvQT09* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/UPvaJBcnB9yu8Re-TR7dBnNYNJyWPZXbUf…> Meeting ID: 812 8891 5014 Passcode: 967992 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/iyOIzzg_nVx7Bu3-NolrUvwYpV1JmU_hFp…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Et9Pc4YQXTY89y_CV5p_IUhO4DxipOFuoI…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/yVeI_QEUL9xx9EqhVQgfTjU0cwCU5_VhvC…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/0kMzTVLZsJ-Syk4mMhudyxU14AXIlPy9yW…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/QYDynuy101bf3yF94teX10r5klyqsB8YBx…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/qnxIbHpfFwuutvK3uttAeswc2cRYOxE0tz…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/_BlSIp8G775XAxS37E-KhH0lDg1opLCsE-…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

(PMS)^2 online talk: Lucia Caramellino [Monday June 28 at 5:30pm]
by Maurizia Rossi 23 Jun '21

23 Jun '21

Dear colleagues, we are happy to announce the following online talk: Speaker: *Lucia Caramellino* (Università di Roma "Tor Vergata") Title: *Regularization lemmas and convergence in total variation.* Abstract: We provide a simple abstract formalism of integration by parts under which we obtain some regularization lemmas. These lemmas apply to any sequence of random variables which are smooth and non-degenerated in some sense and enable one to upgrade the distance of convergence from a smooth (Wasserstein e.g.) distance to the total variation in a quantitative way. We provide a result removing the costly assumption that some non-degeneracy is required along the whole sequence, as we require only non-degeneracy at the limit. The price to pay is to control the smooth distance between the Malliavin matrix of the sequence and the Malliavin matrix of the limit which is particularly easy in the context of Gaussian limits as their Malliavin matrix is deterministic. We show some applications of this result. >From joint papers with Vlad Bally and Guillaume Poly. Date and time: * Monday June 28, 17:30-18:30 (Rome time zone)* *Zoom link: * https://us02web.zoom.us/j/82036797456?pwd=bFpXZndKOHFxOTNrUkd0OVhub09qZz09 ID riunione: 820 3679 7456 Passcode: t0Db9B This is a talk of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics *organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale.

Fwd: [owps] OWPS Talks June 24
by Faggionato, Alessandra 23 Jun '21

23 Jun '21

Buongiorno vi giro l'annuncio del OWPS di domani (notate che nella mail scrivono June 25 ma poi hanno mandato una seconda mail di rettifica). Buona giornata Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 23 giu 2021 alle ore 08:14 Subject: [owps] OWPS Talks June 25 To: <owps(a)lists.bath.ac.uk> Dear All, Thursday June 25 we have a session on Probability Theory and Population Genetics, Speakers: Cornelia Pokalyuk and Anton Wakolbinger. This is the last session before the summer break! (Note: the time is in UTC. Due to time changes, you should check what that translates to in your location) ------------------------------------------------ (14:00-16:00 UTC) Speakers: Cornelia Pokalyuk and Anton Wakolbinger Fixation of slightly beneficial alleles from a backward and a forward perspective Cornelia Pokalyuk and Anton Wakolbinger (Goethe Universität Frankfurt) For a slightly beneficial mutant whose mean offspring number is by a factor 1+s larger than that of the wild types, the probability of being established in a large population is \approx 2s/v^2, where v^2 is the offspring variance. This approximation has been derived (for v^2=1) by Haldane (1927). In our tandem talk we will present some mathematics behind and beyond Haldane's formula within the class of Cannings models (which in the neutral case generalize the prototypic Wright-Fisher model from multinomial to exchangeable offspring numbers). It turns out that for ``moderately strong'' selection the {\em forward perspective} of the Galton-Watson approximation helps to prove the Haldane asymptotics in the large population limit, whereas for ``moderately weak'' selection a {\em backward perspective} is appropriate, which relies on an ancestral selection graph in discrete time. These parts of the presentation are based on F. Boenkost, A. Gonz\’alez Casanova, C.P., A.W., Haldane's formula in Cannings models: - The case of moderately weak selection, Electron. J. Probab. 26(4) (2021) - The case of moderately strong selection, arXiv:2008.02225 [1] [math.PR], submitted. In the last part of the talk we will give an outlook on work in progress on analoga of Haldane's formula for a class of Cannings models with asymptotically infinite offspring variance. A.

17 Jun '21

Care/i iscritte/i, il Dipartimento di Scienze di Base e Applicate per l'Ingegneria di "Sapienza Università di Roma" bandisce un *assegno di ricerca di categoria B - tipologia I* annuale (rinnovabile) dal titolo "*Analisi e sviluppo di modelli per l'interazione tra molecole di DNA e substrato nanostrutturato*" all'interno del Progetto DIANA - "DIAgnostic potential of disorder: development of an innovative NAnostructured platform for rapid, label-free and low-cost analysis of genomic DNA" (IT) Il progetto di ricerca riguarda lo sviluppo e l’applicazione di tecniche statistiche finalizzate allo studio di dati spettrali ottenuti dall’analisi per deposizione diretta della soluzione contenente le molecole target di DNA genomico su vetrini standard da microscopia appositamente ricoperti dalle nanostrutture sonda e letti da apparati Raman. In particolare, al fine di analizzare i risultati sperimentali, saranno applicati diversi metodi statistici per ridurre ed interpretare i dati ottenuti, come ad esempio l’Analisi in Componenti Principali (ACP) o l’Analisi Fattoriale (AF). L’obiettivo sarà quello di individuare eventuali clusters di dati associati a possibili esiti nell’ambito della diagnostica del DNA in campo oncologico. Ulteriore finalità sarà quindi quella di sviluppare modelli predittivi, in grado di individuare l’appartenenza ad un determinato cluster di nuovi dati. Il lavoro di analisi statistica sarà sviluppato mediante uno o più linguaggi di programmazione (R Cran, Python, Matlab...). (EN) The research project regards the development and the application of statistical techniques aimed to study spectral data obtained by the analysis of spectral data from the direct deposition of the solution containing target molecules of genomic DNA on standard microscopy slides covered by the probe nanostructures and read by Raman machines. In particular, to analyze the experimental results, several different methods will be applied to the data, such as Principal Component Analysis (PCA) and Factorial Analysis (FA). The target is to identify potential clusters of data related to possible outcomes in the setting of DNA diagnostic in the oncology framework. Another goal is to develop predictive models, to identify the belonging of new data to a given cluster. The work of statistical analysis will be performed within one or more programming languages (R Cran, Python, Matlab...) La scadenza del bando è il *17 Luglio 2021* Maggiori informazioni, bando e materiale per la domande sono reperibili qua https://web.uniroma1.it/trasparenza/dettaglio_bando_albo/178055/2021-07-17T… Cordiali saluti -- Claudio Durastanti Dipartimento di Scienze di Base Applicate per l'Ingegneria La Sapienza - Università di Roma Via Antonio Scarpa 16 00161 Roma -- ________________________________________________________ Le informazioni contenute in questo messaggio di posta elettronica sono strettamente riservate e indirizzate esclusivamente al destinatario.
