We are pleased to announce that during the week of November 24th to 28th, we will have a series of colloquia for the PhD in Mathematics and Modeling at the University of L'Aquila, according to the following schedule
*************************************
Monday November 24; 16.30--17.30; Aula Seminari Turing building
Speaker: Carlangelo Liverani (University of Roma 2)
Title: Divination is hard, but on average …
Abstract: will discuss the phenomenon of instability with respect to initial conditions and attempt to explain why, in certain cases, probabilistic ideas can be helpful.
*********************************************
Tuesady November 25; 16.30--17.30; room A1.2 Turing building
Speaker: Claudio Landim (IMPA, Rio de Janeiro)
Title: Metastability of Markov processes
Abstract: Metastability is a physical phenomenon ubiquitous in first order phase
transitions. A tentative of a precise description can be traced back,
at least, to Maxwell at the end of the XIX century.
In the mid-1980s, Cassandro, Galves, Olivieri and Vares,
in the sequel of Lebowitz and Penrose, proposed a first
rigorous method for deducing the metastable behavior of Markov
processes, based on the theory of large deviations developed by
Freidlin and Wentsel. This method, known as the
pathwise approach to metastability, was successfully applied to
many models in statistical mechanics.
In the following years, different approaches were put forward. In this talk
we review some recent results in this field. In particular, we show that
the metastable behavior of a sequence of
Markov chains can be read from a property of the solutions of the
resolvent equation associated with the generator of the process. It
turns out that this property is not only sufficient, but also
necessary for metastability.

Wednesday November 26; 16.30--17.30; Aula Seminari Turing building
Speaker: Pedro L. Garrido (Universidad de Granada)
Title: NONEQUILIBRIUM STATISTICAL MECHANICS: A PERSONAL OVERVIEW
Abstract: Nonequilibrium statistical mechanics deals with interacting $N$-particle systems subjected to external agents that generate currents within the system.
We are interested in the stationary states reached by such systems after their long-time evolution from an initial configuration. We will introduce some basic concepts and focus on recent studies to present theoretical and numerical strategies that help characterize their behavior.
In particular, we will discuss the classical anharmonic chain under the action of an external periodic forcing, how to obtain the stationary distribution by solving a Hamilton–Jacobi equation, and the importance of numerical experiments for gaining precise insight into these complex systems.

"Anomalous Regularization in Kazantsev-Kraichnan Model "
Date: November 10th (Monday) at 2.30 pm.
on site: at the GSSI Main Lecture Hall ( viale crispi 7)
zoom: https://gssi-it.zoom.us/j/87571297606pwd=uaKzpEsOHBPbP9D2XxbNsbnYGoBbsk.1
Meeting ID: 875 7129 7606
Passcode: SMAQ2526
Abstract
Abstract
We investigate a passive vector field which is transported and stretched by a divergence-free Gaussian velocity field, delta-correlated in time and poorly correlated in space (spatially nonsmooth). Although the advection of a scalar field (Kraichnan's passive scalar model) is known to enjoy regularizing properties, the potentially competing stretching term in vector advection may induce singularity formation. We establish that the regularization effect is actually retained in certain regimes. While this is true in any dimension $d\ge 3$, it notably implies a regularization result for linearized 3D Euler equations with stochastic modeling of turbulent velocities, and for the induction equation in magnetohydrodynamic turbulence.
The presentation is based on a joint work with Francesco Grotto and Mario Maurelli.
