Random walk on the East model (and other environments with spectral gap)

The East model is a one-dimensional interacting particle system with non attractive spin-flip dynamics. In the physics literature, it is a key example of a model with glassy features. Here we take thi...

Mathematical Methods and Inventive Engineering

 Abstract: Engineering, intended as the capability of producing innovation and new technology, pays an important tribute to mathematics. It is well known how the increasing computer power open th...

Mechanics of out-of-plane deformation patterns in supported graphene

Abstract: Graphene is a two-dimensional material with a unique set of properties, many of which rely on its planar two-dimensional structure. In many applications, graphene is supported on a substrate...

Appearance Fabrication: An Optimization Approach

Abstract: Today’s 3D printers are likely to revolutionize personal fabrication, with their hardware improving everyday and their cost getting lower. In this walk, I will present my work in using 3D pr...

Large time behavior for diffusion equations in unbounded domains

The asymptotic decay rate and other qualitative features of solutions to parabolic equations set in noncompact domains of RN, or Riemannian manifolds, depend in general on a suitable notion of the geo...

Geometric problems related to the inhomogeneous infinity Laplace equation

We discuss some recent results related to the homogeneous Dirichlet problem for the infinity Laplace equation with constant source in a bounded domain. We characterize the geometry of domains for whic...

On the theory of relaxation for variational problems with constraints on the determinant

We consider vectorial variational problems of the form E[u]=∫W(Du)dx, typical for example of nonlinear elasticity and plasticity, which include constraints on the determinant. Specifically, the ener...

On a long range segregation model

Segregation phenomena occurs in many areas of mathematics and science: from equipartition problems in geometry, to social and biological processes (cells, bacteria, ants, mammals) to finance (sellers ...

Asymptotic behaviour of a semilinear elliptic equation

The well-studied power-law-nonlinearity elliptic PDE is known to exhibit a variety of interesting effects, including non-existence, non-uniqueness and concentration phenomena. The application of forma...

Periodic and quasi-periodic solutions in nearly-integrable Hamiltonian systems

In 1892 H. Poincaré conjectured that periodic orbits are dense in the phase space of a general (analytic) nearly-integrable Hamiltonian systems. I shall discuss a weaker "asymptotic" version of Poinc...

A gradient flow approach to large deviations for diffusion processes

In the 80s, De Giorgi introduced the notion of abstract gradient flows, which allowed to define a notion of solutions to ordinary differential equations of the form x' = −grad F(x) on metric spaces ...

Endpoint regularity of 2-d Mumford-Shah minimizers

We discuss an epsilon-regularity result at the endpoint of connected arcs for 2-dimensional Mumford-Shah minimizers obtained in a joint work with C. De Lellis (U. Zuerich). As an outcome of our analys...
