[PRISMA] seminari di Paolo Dai Pra e Alberto Chiarini
by Domenico Marinucci 03 Nov '22

03 Nov '22

Cari colleghi i seminari del gruppo UMI Prisma riprenderanno a partire da Novembre con il calendario consueto (primo lunedì del mese, ore 16-18, online su piattaforma Teams). Qui sotto i dettagli del prossimo incontro (Paolo Dai Pra e Alberto Chiarini), grazie per l'attenzione, Domenico Marinucci * November 7, 2022, 16:00-17:00 (CET): Paolo Dai Pra TITLE: Noise-induced periodicity in stochastic dynamics: some examples ABSTRACT: The emergence of periodic behavior in the dynamics of several interacting components is a common pattern of self-organisation in living systems. Rigorous mathematical treatments are still limited to few examples. In this talk we review some of these examples, emphasizing the essential role of the noise in the appearance of regular rhythms. * November 7, 2022, 17:00-18:00 (CET): Alberto Chiarini TITLE: How costly is it for a simple random walk to cover a fraction of amacroscopic body? ABSTRACT: In this talk we aim at establishing large deviation estimates for the probability that a simple random walk on the Euclidean lattice (d>2) covers a substantial fraction of a macroscopic body. It turns out that, when such rare event happens, the random walk is locally well approximated by random interlacements with a specific intensity, which can be used as a pivotal tool to obtain precise exponential rates. Random interlacements have been introduced by Sznitman in 2007 in order to describe the local picture left by the trace of a random walk on a large discrete torus when it runs up to times proportional to the volume of the torus, and has been since a popular object of study. In the first part of the talk we introduce random interlacements and give a brief account of some results surrounding this object. In the second part of the talk we study the event that random interlacements cover a substantial fraction of a macroscopic body. This allows to obtain an upper bound on the probability of the corresponding event for the random walk. Finally, by constructing a near-optimal strategy for the random walk to cover a macroscopic body, we discuss a matching large deviation lower bound. The talk is based on ongoing work with M. Nitzschner (NYU Courant).

Seminario di Gianni Pagnini a Napoli
by Enrica Pirozzi 30 Oct '22

30 Oct '22

--- AVVISO di SEMINARIO Dr. Gianni Pagnini BCAM & Ikerbasque, Bilbao, Spain Title: Fractional diffusion as an intermediate asymptotic regime. Abstract: A continuous-time random walk driven by two different Markovian hopping-trap mechanisms is investigated and it is shown that the paradigmatic features of anomalous diffusion are met. More precisely, anomalous diffusion results from a process that goes through the action of two co-existing Markovian mechanisms acting with different statistical frequency, and the probability of occurrence of this switch between the two Markovian settings originates and fully characterises the anomalous diffusion. In fact, ensemble and single-particle observables of this model have been studied and they match the main characteristics of anomalous diffusion as they are typically measured in living systems. In particular, the celebrated transition of the walker?s distribution from exponential to stretched-exponential and finally to Gaussian distribution is displayed by including also the Brownian yet non-Gaussian interval. Moreover, the model dynamically provides the power-law exponent of the mean-square displacement as a function of the probability of switching between the two Markovian states, namely the fractional order. Hence, fractional diffusion emerges as an intermediate asymptotic regime. Finally, within the present approach, fractional diffusion can be interpreted as a mathematical method for bridging two co-existing equilibrium states in a disordered medium. This talk is based on: Vitali S, Paradisi P and Pagnini 2022 J. Phys. A: Math. Theor. 55 224012 Il seminario si terrà il giorno 3 Novembre 2022 ore 16:00 nella Aula D primo livello del Dipartimento Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli. -- Link per seguire online: https://teams.microsoft.com/l/meetup-join/19%3aMQ4RZDBo_0G-K_PHxKtktVYAczOG… -- Enrica Pirozzi Dipartimento di Matematica e Applicazioni Universita' di Napoli FEDERICO II Via Cintia, Monte S.Angelo, 80126, NAPOLI, ITALY Tel. 081 675634 https://www.docenti.unina.it/ENRICA.PIROZZI

28 Oct '22

Buongiorno, Ricevo ed inoltro. Buon weekend Alessandra ---------- Forwarded message --------- Da: Louigi Addario-Berry <louigi(a)gmail.com> Date: ven 28 ott 2022, 16:52 Subject: Graduate and postdoctoral opportunities To: Louigi Addario-Berry <louigi(a)gmail.com> Dear colleagues, I would appreciate it if you could circulate the below information to your networks. I am planning to recruit two new doctoral students (beginning in September 2023) and some positive number of new Master's students (also beginning in September 2023). Also, there are multiple postdoctoral opportunities available at McGill and in Montreal (beginning in May 2023 or later). Those who are interested in a postdoctoral position should apply to the following postings: November 11 deadline: https://www.mathjobs.org/jobs?joblist-1067-20525 December 15 deadline: https://www.mathjobs.org/jobs/list/21313 Those who are interested in a doctoral position should apply here: January 15 deadline: https://www.mcgill.ca/gradapplicants/how-apply In both cases, applicants should mention my name as a potential supervisor. Applicants who would like to work with me should be interested in probability and its interactions with other subjects (e.g. combinatorics, graph theory, PDEs), and should ideally have background in some of these areas. However, all applications will be carefully considered, including from those with non-traditional academic trajectories. Applicants can find out some things about my research interests on my website: http://problab.ca/louigi/. They are also welcome to contact me in advance of applying if they have questions. I especially welcome applications from members of groups who are traditionally underrepresented within mathematics. Sincerely, Louigi.

Seminar Van Bever at UPO
by Enea Bongiorno 28 Oct '22

28 Oct '22

Dear colleagues, We are glad to invite you to the seminar that will take place on the 8th of November, at 16.00: - in presence: room 201 of the campus Perrone, via Perrone, 18, Novara Università del Piemonte Orientale, Dipartimento di Studi per l’Economia e l’Impresa. - on-line at the link: meet.google.com/yvq-ccbt-pzt Prof. Germain Van Bever Université de Namur, Belgio Title: Flexible Hilbertian Additive Regression with Small Errors-in-Variables Abstract: In this talk, we present a new framework of additive regression modelling for data in very generic settings. More precisely, we tackle the problem of estimating component functions of additive models where the regressors and/or response variable belong to general Hilbert spaces and can be imperfectly observed. By this,we mean that some variables can be either measured incompletely or with errors. Smooth backﬁtting methods are used to estimate consistently the component functions and we provide explicit rates of convergence. We amply illustrate our methodology in various settings, including the functional, Riemannian and Hilbertian settings.
