Metric regularity in optimal control

I will start with brief introduction to the concept of metric regularity and some applications for optimal control problems. Then we focus on linear control systems, where we introduce the notion of b...

Criteria for the Poincare-Hardy inequalities

This is a survey of old and new necessary and sufficient conditions for validity of various integral inequalities containing arbitrary weights (measures and distributions). These results have direct a...

Relative entropy methods and relaxation limits

We shall analyze relative entropy methods in connections with singular limits, both for the hyperbolic-to-hyperbolic and for the hyperbolic-to-parabolic relaxations. For the former case, we recall in ...

Error estimate for second order Hamilton-Jacobi-Bellman equations with unbounded coefficients. Application to chance-constrained control problems

In this talk we shall present numerical approximations of unbounded value functions associated to some stochastic control problems. We derive new error estimates for monotone schemes based on Markov c...

Reachability analysis and general control problems

In this talk, we will review some known results on the link between reachability analysis and optimal control problems in the deterministic setting. We will show how this link can be used to get a con...

A comparison between different cycle decompositions for Metropolis dynamics

In the last decades the problem of metastability has been attacked on rigorous grounds via many different approaches and techniques which are briefly reviewed in this paper. It is then useful to under...

Quasilinear elliptic problems with quadratic gradient term. Comparison principle and Gelfand problems

We review some recent results concerning with the existence of positive solutions of the following problem \begin{cases} \displaystyle -\Delta u +H(x,u,\nabla u)= \lambda f(u) \quad & \mbox{in}\,\...

Analog Digital Belief Propagation and its application to channel decoders

Abstract: As required by information theory, channel codes with long code words are necessary building blocks in a transmission system to achieve reliable communications with minimal power and maximal...

Some mass transport problems as limits of p-Laplacian problems

Following the method introduced by Evans y Gangbo to solve the classical Monge-Kantorovich mass transport problem, in this lecture we present two mass transport problems obtained as limit when p\to \i...

Generalization of Arakawa's Jacobian

There are several well known methods to discretize, by finite differences, the vorticity equation for two-dimensional incompressible flow, but Arakawa's Jacobian is one of the most renowned solutions ...

Unique tangent cones for 2-d almost minimal currents

In this talk I will discuss some new results on the infinitesimal behavior of 2 dimensional almost minimal surfaces (relevant examples are semi-calibrated currents and section of 3 dimensional minimiz...
