Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The two talks will be accessible under the link Click here to join the meeting<https://teams.microsoft.com/l/meetup-join/19%3Aaf3d635091e049579e555a84219a…> Best regards, Giacomo Tuesday, April 13, 16:00 Speaker: Laure Dumaz (École Normale supérieure) Title: Localization of the continuous Anderson hamiltonian in 1-d and its transition towards delocalization. Abstract: We consider the continuous Schrödinger operator - d^2/d^x^2 + B’(x) on the interval [0,L] where the potential B’ is a white noise. We study the entire spectrum of this operator in the large L limit. We prove the joint convergence of the eigenvalues and of the eigenvectors and describe the limiting shape of the eigenvectors for all energies. When the energy is much smaller than L, we find that we are in the localized phase and the eigenvalues are distributed as a Poisson point process. The transition towards delocalization holds for large eigenvalues of order L. In this regime, we show the convergence at the level of operators. The limiting operator in the delocalized phase is acting on R^2-valued functions and is of the form ``J \partial_t + 2*2 noise matrix'' (where J is the matrix ((0, -1)(1, 0))), a form appearing as a conjecture by Edelman Sutton (2006) for limiting random matrices. Joint works with Cyril Labbé. Tuesday, April 13, 17:00 Speaker: Martin Vogel (Université de Strasbourg) Title: Eigenvalue asymptotics and eigenvector localization for non-Hermitian noisy Toeplitz matrices Abstract: A most notable characteristic of non-Hermitian matrices is that their spectra can be intrinsically sensitive to tiny perturbation. Although this spectral instability causes the numerical analysis of their spectra to be extremely unreliable, it has recently been shown to be also the source of new mathematical phenomena. I will present recent results about the eigenvalues asymptotics and eigenvector localization for deterministic non-Hermitian Toeplitz matrices with small additive random perturbations. These results are related to recent developments in the theory of partial differential equations. The talk is based on joint work with J. Sjöstrand, and with A. Basak and O. Zeitouni. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

Avviso di Seminario - PRISMA
by Domenico Marinucci 06 Apr '21

06 Apr '21

Cari Colleghi lunedì prossimo 12 Aprile dalle 16 alle 18 avrà luogo il prossimo incontro per il ciclo di seminari Prisma. Gli speaker saranno Marco Fuhrman e Andrea Cosso, qui sotto titoli, abstract ed il link al collegamento Teams. ---------------------------------------------------------------- Speaker: Marco Fuhrman (Università di Milano) Title: A new tool in stochastic optimal control: the randomization method. Abstract: In the first part of this talk I will present a survery on the relationships among classical stochastic optimal control problems, non-linear partial differential equations (the Hamilton-Jacobi-Bellman equations) and backward stochastic differential equations (BSDEs). In the second part, more specifically, I will introduce the so-called randomization method, which allows to associate an appropriate BSDE to a large class of optimal control problems. Among the possible generalizations, I will concentrate on optimal control of path-dependent equations, i.e. equations with general with memory effects. Speaker: Andrea Cosso (Università di Bologna) Title: Randomization method and path-dependent Hamilton-Jacobi-Bellman equation Abstract: In the present talk I will study a stochastic optimal control problem with path-dependent coefficients. I will exploit the so-called randomization method to derive a dynamic programming principle for the value function. This allows to prove that the value function is a viscosity solution to a path-dependent Hamilton-Jacobi-Bellman equation, involving the horizontal and vertical derivatives of functional Ito calculus. Finally, I will discuss the validity of the comparison principle for such a partial differential equation.

Webinar in Statistics GILLES STUPFLER

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 9 Aprile 2021, alle ore 12.00, si terrà il seguente webinar: ------------------------------------------------ Speaker: *Gilles Stupfler *(ENSAI Rennes and CREST, France) Title: *Asymmetric least squares techniques for extreme risk estimation* Zoom link: https://us02web.zoom.us/j/81720792366?pwd=QWtaYVRRejVSVGlOMXFMaDdsemxjdz09 Meeting ID: 817 2079 2366 Passcode: 241135 Abstract: Financial and actuarial risk assessment is typically based on the computation of a single quantile (or Value-at-Risk). One drawback of quantiles is that they only take into account the frequency of an extreme event, and in particular do not give an idea of what the typical magnitude of such an event would be. Another issue is that they do not induce a coherent risk measure, which is a serious concern in actuarial and financial applications. In this talk, I will explain how, starting from the formulation of a quantile as the solution of an optimisation problem, one may come up with two alternative families of risk measures, called expectiles and extremiles. I will give a broad overview of their properties, as well as of their estimation at extreme levels in heavy-tailed models, and explain why they constitute sensible alternatives for risk assessment using some real data applications. This is based on joint work with Abdelaati Daouia, Irène Gijbels, Stéphane Girard and Antoine Usseglio-Carleve. ------------------------------------------------ Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>
