A Summer Day in Probability and Statistical Physics
by Francesca Romana Nardi 16 Nov '18

16 Nov '18

Carissimi, la prossima giornata di seminari sara` il 14 Settembre 2018. Ricordo che ciascuno oratore fara` una lezione introduttiva e divulgativa di 45 minuti pensata proprio per i non esperti, seguita da altri 45 minuti di tipo seminario (vedi programma). Maggiori informazioni e aggiornamenti sulle giornate passate e future sono reperibili alla pagina web che vi invitiamo a visitare periodicamente. http://web.math.unifi.it/users/fnardi/seminari/ A SUMMER DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 14 September 2018 Lecturers: Stefano Olla (Paris) and Raúl Rechtman (Mexico) Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Stefano Olla (Universite` Paris Dauphine) Title: Hyperbolic Hydrodynamic Limits Abstract: I will present a review of old and new results (and open problems) concerning scaling limits for conservation laws in the hyperbolic space-time scale, for a system of anharmonic oscillators with external boundary tension. The macroscopic equation is given by the compressible Euler system, with corresponding boundary conditions. The problem is particularly challenging when shockwaves are present. Some results exists when the microscopic dynamics is perturbed by a conservative stochastic viscosity. Works in Collaboration with Stefano Marchesani (GSSI) and Lu Xu (CEREMADE). Prof. Raúl Rechtman, (Universidad Nacional Autónoma de México) Title: Chaos and damage spreading in a probabilistic cellular automaton Abstract: Deterministic Boolean cellular automata (CA) are discrete maps F:BN → BN, B={0,1}, x(t+1)=F(x(t)) with x ϵ BN, N large and t=0,1,… . The vector x is the state of the cellular automaton with components xi,, i=0,…,N-1 the state of cell I. Each cell is connected to others, generally in a uniform and local way, and one can define an adjacency matrix aij=1 is cell j is connected to cell i and zero otherwise. The global map F is determined by the parallel application of a local function f, such that xi(t+1) = f(vi(t)), where vi denotes the state of cells connected to cell i. Deterministic CA are thus the discrete equivalent of dynamical systems, and many concepts like trajectory (the sequence of configurations x(t)), fixed points and limit cycles can be used. There are cellular automata for which a small modification in an initial configuration propagates to the whole system, a situation similar to chaos in continuous systems, and indeed one can extend the concept of the largest Lyapunov exponent to deterministic CA using Boolean derivatives. One of the main inconvenient is that these systems do not have continuous parameters to be tuned, in order to study bifurcations. In probabilistic cellular automata, the function f (and thus F) is defined in terms of transition probabilities so that deterministic CA can be seen as the extreme cases of probabilistic ones, when the transition probabilities are either zero or one. Probabilistic CA can be seen also as Markov chains, and one can observe interesting phase transitions after changing the transition probabilities that are therefore continuous control parameters. A realization of a specific trajectory is determined by the extraction of one or more of random numbers for each cell. By extracting these numbers at the beginning of the simulation, for all cells and all times, one converts a probabilistic CA into a deterministic one, running over a quenched random field. One can therefore use the concepts of deterministic CA, like damage spreading and maximum Lyapunov exponent also for probabilistic CA, with the advantage of having the possibility of fine-tuning the control parameters. In particular, we investigate a probabilistic cellular automaton which can be considered an extension of a model in the universality class of directed percolation models, but with two absorbing states. In the first part of the talk all the concepts mentioned above are defined and in the second part, the probabilistic cellular automaton is studied numerically. We show that the phase transitions when the order parameter is the average damage do not coincide with those found for the Lyapunov exponent and the reason of this is the presence of absorbing states.

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 5 Ottobre 2018, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Fernando A. QUINTANA (Pontificia Universidad Catolica de Chile) DISCOVERING INTERACTIONS USING COVARIATE INFORMED RANDOM PARTITION MODELS Combination chemotherapy treatment regimens created for patients diagnosedwith childhood acute lymphoblastic leukemia have had great success inimproving cure rates. Unfortunately, patients prescribed these types oftreatment regimens have displayed susceptibility to the onset ofosteonecrosis. Some have suggested that this is due to pharmacokineticinteraction between two agents in the treatment regimen (asparaginase anddexamethasone) and other physiological variables. Determining whichphysiological variables to consider when searching for interactions inscenarios like these, minus a priori guidance, has proved to be achallenging problem, particularly if interactions influence the responsedistribution in ways beyond shifts in expectation or dispersion only. We propose an exploratory technique that is able to discoverassociations between covariates and responses in a very general way. Theprocedure connects covariates to responses very flexibly through dependentrandom partition prior distributions, and then employs machine learningtechniques to highlight potential associations found in each cluster. Weapply the method to data produced from a study dedicated to learning whichphysiological predictors influence severity of osteonecrosis multiplicatively. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare.

Seminario Prof. N. Leonenko - Roma
by Luisa Beghin 28 Sep '18

28 Sep '18

*Seminario congiunto Università Sapienza - Tor Vergata, Roma* *Mercoledì 3 ottobre 2018* Ore 15:00, Aula 34 (iv piano) Dipartimento di Scienze Statistiche, Sapienza *Titolo: *Limit theorems, scaling of moments and intermittency for integrated finite variance supOU processes *Speaker:* Prof. N. Leonenko (Cardiff University, UK) *Abstract:* Superpositions of Ornstein-Uhlenbeck type (supOU) processes provide a rich class of stationary stochastic processes for which the marginal distribution and the dependence structure may be modeled independently. In this paper we investigate the limiting behavior of integrated supOU processes with finite variance. We show that after suitable normalization four different limiting processes may arise. The type of limit depends on the decay of the correlation function as well as on the characteristic triplet of the marginal distribution. SupOU processes, moreover, may exhibit intermittency, a phenomenon affecting the rate of growth of moments. We establish this rate for each of the four limiting scenarios. The rate changes at some point indicating that there is a change-point in the asymptotic behavior of absolute moments. For such a behavior to be possible, the moments in the limit theorem do not converge beyond some critical point. We show that this point is related to the dependence structure of the supOU process. The intermittency phenomenon appears also in some other models, for example, Intermittency of trawl processes. Joint work with D. Grahovac (Osijek University, Croatia) and M. Taqqu (Boston University, USA). Tutti gli interessati sono invitati ad intervenire. Cordiali saluti.

Martedi` 2 Ottobre, ore 14.00 Aula di Consiglio, Dipartimento di Matematica, La Sapienza Speaker: F. Patras (University of Nice) Title: Revisiting chaos expansions and Wick products Abstract: Recently, the interest in the structure of cumulants and Wick products for non-Gaussian variables has been revived, since they both play important roles in M. Hairer’s theory of regularity structures. We present a new approach to the theory based on tools (group actions, Hopf algebras) that allow to understand the theory of Wick products as a deformation, a presentation from which many of their properties follow easily. We also discuss how these ideas appear in the theory of regularity structures. Based on j.w. with K. Ebrahimi-Fard, N. Tapia, L. Zambotti.

Seminario F. Caravenna - Univ. Bocconi, Milano
by Antonio Lijoi 24 Sep '18

24 Sep '18

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

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.

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.
