I will consider long time influence of small deterministic and stochastic perturbations of various dynamical systems and stochastic processes. The long time evolution of the perturbed system can be described by a motion in the cone of invariant measures of the non-perturbed system. The set of extreme points of the cone can be often parametrizedb...

We consider the nonlinear Schrodinger equation either with full or partial harmonic trapping. In both cases, the long-time behavior is heavily influenced by the resonant part of the dynamics, which we shall define and study. In the case, when all directions but one are trapped ("cigar-shaped" trapping), we prove modified scattering of the nonlin...

We investigate the properties of a model describing the motion of liquid drops sitting on a flat surface. Here we consider the so-called quasi-static approximation model, where the speed of the contact line between the fluid and the surface is much slower than the capillary relaxation time.We show that, under a geometric constraint on the initia...

We discuss the long time average of Mean Field Games systems as the time horizon tends to infinity and the convergence towards a stationary ergodic mean field game, both in case of local and nonlocal coupling in the cost functional.We also prove that convergence holds at exponential rate, exploiting two completely different approaches; in case o...

Data science, machine learning, and artificial intelligence are all practices implemented by humans in the context of a complex and ever-changing world. This talk will focus on the challenges of long-term, seasonal, multicyclic time series forecasting in logistics. I will discuss algorithms and implementations including STL, TBATS, and Prophet, ...

This talk will survey some recent developments in the theory of nonlineardispersive evolution equations, with emphasis on a qualitative description ofthe global-in-time dynamics of solutions. We will present the method of concentration compactness which has lead to important advances during the pastsix years. These results cannot be obtained by ...
