Minimization of Degenerate Nonlinear Functionals under Radial Symmetry

Valeria Chiadò Piat, Virginia De Cicco, Anderson Melchor Hernandez

In this work, we study the minimization of nonlinear functionals in dimension that depend on a degenerate radial weight . Our goal is to prove the existence of minimiz…

Relaxation for a degenerate functional with linear growth in the onedimensional case

Valeria Chiadò Piat, Virginia De Cicco, Anderson Melchor Hernandez

In this work, we study the relaxation of a degenerate functional with linear growth, depending on a weight that does not exhibit doubling or Muckenhoupt-type conditions. In ord…

An extension theorem from connected sets and homogenization of non-local functionals

Andrea Braides, Valeria Chiadò Piat, Lorenza D'Elia

We study the asymptotic behaviour of convolution-type functionals defined on general periodic domains by proving an extension theorem

The stiff Neumann problem: asymptotic specialty and "kissing" domains

V. Chiadò Piat, L. D'Elia, S. A. Nazarov

We study the stiff spectral Neumann problem for the Laplace operator in a smooth bounded domain which is divided into two subdomains: an annulus and a…

Discrete double-porosity models

Andrea Braides, Valeria Chiado Piat, Andrey Piatnitski

We study a discrete-to-continuous Gamma-limit of a family of high-contrast double porosity type functionals defined on a scaled integer lattice. Under periodicity and p-growth cond…

Localization effect for a spectral problem in a perforated domain with Fourier boundary cconditions

Valeria Chiado Piat, Iryna Pankratova, Andrey Piatnitski

We consider a homogenization of elliptic spectral problem stated in a perforated domain, Fourier boundary conditions being imposed on the boundary of perforation. The presence of a…
