Homogenisation of nonlinear Dirichlet problems in randomly perforated domains

In this talk we present some recent results on the convergence of nonlinear Dirichlet problems for systems of variational elliptic PDEs defined on randomly perforated domains of Rn. Under the assumpti...

Non-local approaches to effective energies for materials' singularities

We discuss in two relevant case-studies the rigorous derivation via Gamma-convergence of asymptotic energies accounting for singularities in elastic materials from non-local models (convolution-type i...

OT methods for parabolic diffusion equations: the JKO scheme

This mini-course is concerned with those PDEs which have a gradient flow structure in the Wasserstein space W_2 and can thus be attacked via the so-called Jordan-Kinerlehrer-Otto scheme, a sequence of...

Shape optimization problems for nonlocal anisotropic energies

Nonlocal shape optimization problems involving interaction energies with competing repulsive and attractive terms are of interest in a variety of applications and have been extensively studied in the ...

Gradient flows for variational inference and their deterministic, interacting-particle approximations

Over the recent years deterministic interacting-particle approximations of gradient flows in Wasserstein and other geometries have gained popularity in applications to machine learning and other areas...

On distributions of positive type and applications to QFT

When quantum fields are represented as operators on a Hilbert space, their two-point distributions naturally give rise to distributions of positive type. A number of basic results on such distributi...

A Mountain Pass Theorem and moduli space of minimal immersions

We present a new Mountain Pass Theorem for a class of functionals that depends on two arguments which only partially satisfies the Palais-Smale condition. This abstract functional setup will be a...

On the Dynamical Manin-Mumford problem for plane polynomial endomorphisms

The Dynamical Manin-Mumford problem is a dynamical question inspired by classical results from arithmetic geometry. Given an algebraic dynamical system (X,f), where X is a projective variety and f is ...

Lyndon words and fused currents in shuffle algebra

Classical q-shuffle algebras provide combinatorial models for the positive half U_q(n) of a finite quantum group. We define a loop version of this construction, yielding a combinatorial model for the...

A NOTION OF S-FRACTIONAL MASS FOR 1-CURRENTS IN HIGHER CODIMENSION

We will introduce and discuss a notion of s-fractional mass for 1-currents, generalizing the s-fractional perimeter in the plane to higher codimension singularities. We will present basic compactn...
