DEC-Statistics Seminar @ Bocconi University, Milano Thursday, September 27 12:30 Meeting room 3-e4-sr03, Via Roentgen 1, 3rd floor Francesco Caravenna (Universita' degli studi di Milano - Bicocca) Title: Local large deviations and the strong renewal theorem Abstract: We present two different, but related results for random walks with heavy tails (more precisely: in the domain of attraction of a stable law with infinite mean). The first result is a local large deviation upper bound, which improves on the classical local central limit theorem. The second result is the derivation of necessary and sufficient conditions for the so-called strong renewal theorem, which is the analogue of Blackwell's renewal theorem in the case of infinite mean. This solves a long standing problem, which dates back to a classical paper by Garsia and Lamperti (Comment. Math. Helv. 1962). (Based on joint work with Ron Doney) The DEC statistics seminars schedule is available at http://www.unibocconi.eu/statseminar ---------- Please note: If you are a guest and you do not have a Bocconi ID Card to access to the Bocconi Buildings, please communicate your participation by sending an email to arianna.colombo(a)unibocconi.it In addition, we suggest to print, fill out and send the attached form (to give your consent to personal data handling) via email to the same address.

Seminario di Lorenzo Taggi a Roma Tre il 3/10/18 h16
by Pietro Caputo 24 Sep '18

24 Sep '18

Annuncio di Seminario Speaker: Lorenzo Taggi (TU Darmstadt, Germania) Titolo: Conservative interacting particle systems: "Oil and Water" and "Activated Random Walk". Mercoledi' 03 Ottobre 2018 ORE 16:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Largo San Leonardo Murialdo,1 - Pal.C - Aula 211 Abstract We consider two interacting particle systems, Activated Random Walk (ARW) and Oil and Water (OW). One of the main features of these systems is that the number of particles is conserved: This conservation law introduces hard-core constraints and long-range correlations which make the mathematical analysis particularly challenging. In this talk the main questions and results concerning these models are presented: In ARW, if the particle density is small enough, the activity dies out with time, while if the particle density is large enough the activity is sustained; moreover a non-trivial characterization of the critical density is available. Contrary to ARW, no phase transition occurs in OW: The activity dies out with time does not matter how large the particle density is. Based on joint works with E. Candellero and A. Stauffer.

-------------- AVVISO di SEMINARIO Fractional Pearson Diffusions and Continuous Time Random Walks Prof. N.N. Leonenko School of Mathematics, Cardiff University, UK Abstract: We define fractional Pearson diffusions by non-Markovian time change in the corresponding Pearson diffusions. They are governed by the time-fractional diffusion equations with polynomial coefficients depending on the parameters of the corresponding Pearson distribution. We present the spectral representation of transition densities of fractional Pearson diffusions, which depend heavily on the structure of the spectrum of the infinitesimal generator of the corresponding non-fractional Pearson diffusion. Also, we present the strong solutions of the Cauchy problems associated with heavy-tailed fractional Pearson diffusions and the correlation structure of these diffusions. Continuous time random walks have random waiting times between particle jumps. We define the correlated continuous time random walks (CTRWs) that converge to fractional Pearson diffusions (fPDs). The jumps in these CTRWs are obtained from Markov chains through the Bernoulli urn-scheme model and Wright-Fisher model. The jumps are correlated so that the limiting processes are not Lévy but diffusion processes with non-independent increments. The waiting times are selected from the domain of attraction of a stable law. Il seminario si terrà il giorno 27 Settembre 2018 ore 15:00 nella Aula G terzo livello del Dipartimento Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli.

Seminar at Dep. of Economics - Verona, 27 September 2018, Giacomo Bormetti
by Alessandro Gnoatto 24 Sep '18

24 Sep '18

Dear all, On Thursday 27 September 2018 at 12.00 - Polo Santa Marta, Via Cantarane 24, Sala Vaona Prof. Giacomo Bormetti - University of Bologna will give the seminar "Modeling correlation dynamics with canonical Vines" Abstract: When modeling correlation dynamics, tackling the issue of positive definiteness is a challenging task. At high frequencies in a multivariate financial setting, observational noise and asynchronicity makes the goal even more difficult. After reviewing different observation-driven approaches available in literature, I will focus on a recently proposed modeling framework based on regular vines. Please also find attached the full list of our Finance seminars. Feel free to forward this announcement to your colleagues.

Spring school on Random Interfaces
by Luigi Amedeo Bianchi 19 Sep '18

19 Sep '18

Dear all, this is the first announcement for the spring school on Random Interfaces to be held at the University of Augsburg, Germany, for three full days from March 13th to March 15th, 2019. The school will focus on random interfaces, both continuous (approached by means of stochastic partial differential equations) and discrete (together with their hydrodynamic limits). The school will feature a main course by Tadahisa Funaki (Waseda University/University of Tokyo), a minicourse by Fabio Toninelli (Université Claude Bernard Lyon 1) and an invited lecture by Dimitra Antonopoulou (University of Chester). A poster session for participants is also foreseen. This spring school is intended for PhD students and young researchers, but open for everyone. Registration to the school is free, but compulsory for organisatorial purposes. Limited funds are available to offer financial support to some selected students and young researchers (post-docs). The deadline for application is 15th December 2018. More information and the registration form are available on the website https://www.math.uni-augsburg.de/de/prof/ana/Workshops_Tagungen/Spring-Scho… <https://www.math.uni-augsburg.de/de/prof/ana/Workshops_Tagungen/Spring-Scho…> We are looking forward to seeing you in Augsburg.

I: Avviso di seminario
by Massimo Campanino 18 Sep '18

18 Sep '18

Il giorno 20 settembre alle ore 14 nell'Aula Seminario 2 del Dipartimento di Matematica dell'Università di Bologna in piazza Porta S. Donato 5 il prof. Pietro Rigo del Dipartimento di Matematica dell'Università di Pavia terrà un seminario dal titolo: CLASSICAL VERSUS COHERENT CONDITIONAL PROBABILITIES ABSTRACT: The standard (Kolmogorovian) notion of conditional probability is compared with the (de Finettian) notion based on the coherence principle. Each notion has both merits and drawbacks, and the talk aims to highlight them with special attention to the connection points. Various results, both old and new, are discussed and some open problems are mentioned. The talk is split into four parts. (i) Classical (Kolmogorovian) conditional probabilities; (ii) Disintegrability; (iii) Coherent (de Finettian) conditional probabilities; (iv) Some statistical implications.
