Seminario di F. Hubalek a Milano-Bicocca (03.03.2015)
by Francesco Caravenna 19 Feb '15

19 Feb '15

Martedì 3 marzo 2015 alle ore 15:30, nell'aula 3014 del Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca (edificio U5, via Cozzi 55, Milano), Friedrich Hubalek (TU Wien) terrà un seminario dal titolo Brownian excursion limits for the avalanche length in a binomial limit order book model Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%% Abstract: We briefly describe the mechanics of a stylized limit order book model for an electronic exchange, which is based on the simple symmetric random walk. While the order volume is a spacial process, we take up the study of the avalanche length of trades, that was begun by Thorsten Rheinlaender and his students in a Brownian motion model. By more or less elementary limit calculations we connect to Ito's theory of Brownian excursions. In doing so we briefly, but inevitably meet the error, gamma, zeta, xi, theta, Bessel, and the Gauss hypergeometric function. We derive the generating function for the simplified and full avalanche length, their Brownian limits, and study the distribution of the simplified avalanche length in some detail. This is joint work with Thorsten Rheinlaender and Sabine Sporer. %%%%%%%%%%%%%%%%%% -- _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

Seminario Giovanni Valente al Politecnico di Milano
by Matteo Probo Siro Francesco Gregoratti 19 Feb '15

19 Feb '15

Si avvisa che in data 11-3-2015, alle ore 15:00 , presso Aula Consiglio VII piano, Dipartimento di Matematica, ed. 14, Campus Leonardo, nell'ambito delle iniziative del Dipartimento di Matematica del Politecnico di Milano, si svolgerà il seguente seminario: Titolo: Relativistic Causality and Local Disentanglement in Quantum Field Theory Relatore: Giovanni Valente, University of Pittsbur Abstract: La nozione di entanglement fra sistemi quantistici separati pone due problemi fondamentali in filosofia della meccanica quantistica. Primo, le correlazioni non-locali che ne derivano sembrano determinare un conflitto con la condizione di causalità relativistica, che implica che processi causali non possano propagarsi ad una velocità superiore a quella della luce, sollevando cosí una questione di incompatibilità con la teoria della relatività speciale di Einstein. Secondo, la presenza dell'entanglement sembra pregiudicare la possibilità di ottenere una suddivisione del mondo microscopico in sistemi fisici indipendenti. In questo seminario, si discuteranno tali problemi nel contesto della formulazione algebrica della teoria quantistica dei campi. Si inizierà mostrando come si possa derivare un teorema sull'impossibilità di inviare messaggi superluminali sulla base di operazioni locali. Successivamente, si dimostrerà l'esistenza di operazioni locali che hanno l'effetto di distruggere l'entanglement fra campi quantistici separati, soddisfacendo in tal modo ad una condizione necessaria per la loro indipendenza reciproca.

------------------------------- Messaggio originale -------------------------------- Oggetto: AMS - Mathemical Research Community 2015 in Financial Mathematics Da: "Birgit Rudloff" <brudloff(a)Princeton.EDU> Data: Mer, 18 Febbraio 2015 22:22 ------------------------------------------------------------------------------------ Dear colleagues, This is a first announcement about the upcoming Mathematical Research community (MRC) in Financial Mathematics organized by the American Mathematical Society. The MRC is - in AMS own words- "a program of the American Mathematical Society (AMS), nurtures early-career mathematicians-those who are close to finishing their doctorates or have recently finished-and provides them with opportunities to build social and collaborative networks to inspire and sustain each other in their work. The structured program is designed to engage and guide all participants as they start their careers. For each topic, the program includes a one-week summer conference, a Special Session at the national meeting, a discussion network, ongoing mentoring, and a longitudinal study of early career mathematicians." The MRC in Financial Mathematics consists of a conference June 14 – 20, 2015 in Snowbird, Utah, a session at the Joint Mathematics Meeting, January 6-9, 2016 in Seattle, Washington. Around 40 peridoctoral mathematicians (advanced PhD students and early PostDocs) will work together on topics in high frequency trading, optimal investment under transaction costs, and systemic risk. More information at http://www.ams.org/programs/research-communities/mrc-15. Deadline for applications will be March 1, 2015. Please make your graduate students and Post-Docs aware of this possibility. Note that while American and US-based mathematicians are prioritized, the MRC is open for everybody. Travel support for the Snowbird conference will be available up to USD 700,-. All the best, Maxim Bichuch Michael Carlisle Olympia Hadjiliadis Birgit Rudloff Stephan Sturm

ANNUNCIO SEMINARIO YIMIN XIAO - TOR VERGATA - 25 Febbraio
by Claudio Durastanti 17 Feb '15

17 Feb '15

Ciclo di Seminari - Progetto ERC PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Mercoledì 25 Febbraio ore 16 - Aula Conferenze "Claudio D'Antoni" - Dipartimento di Matematica Università di Tor Vergata - Roma Titolo: Fine Properties of Gaussian Random Fields Speaker: Yimin Xiao - Michigan State University ABSTRACT: In this talk, we show that various properties of strong local nondeterminism can be applied for studying fine properties (e.g. exact moduli of continuity, exact Hausdorff measure functions, regularity of local times and intersection local times) of Gaussian random fields defined on R^N taking values in R^d. Examples of such Gaussian random fields include fractional Brownian motion and solution to certain stochastic heat equations with space-time Gaussian noise. We also show that the method can also be applied to some Gaussian fields on the sphere.

seminario Claudio Macci in Bicocca
by Fabio Bellini 17 Feb '15

17 Feb '15

Il giorno mercoledì 25 febbraio alle ore 16.30 presso l'aula seminari del DISMEQ, al IV piano dell'edificio U7 in piazza dell'Ateneo Nuovo 1, il prof. Claudio Macci del Dipartimento di Matematica della Università di Roma Tor Vergata terrà un seminario su SOME RECENT LARGE DEVIATION RESULTS IN STATISTICS ABSTRACT We consider a family of statistical models with positive unknown parameter (which includes some well-known models for censored exponential data) and some statistical models for samples from stationary Gaussian processes. We prove large deviation results for posterior distributions and, in some cases, also for maximum likelihood estimators. Tutti gli interessati sono invitati a partecipare.
