Low energy configurations of topological singularities in two dimensions: A -convergence analysis of dipoles
Lucia De Luca, Marcello Ponsiglione
This paper deals with the variational analysis of topological singularities in two dimensions. We consider two canonical zero-temperature models: the core radius approach and the G…
Minimising movements for the motion of discrete screw dislocations along glide directions
Roberto Alicandro, Lucia De Luca, Adriana Garroni +1
In [3] a simple discrete scheme for the motion of screw dislocations toward low energy configurations has been proposed. There, a formal limit of such a scheme, as the lattice spac…
Existence and uniqueness for anisotropic and crystalline mean curvature flows
Antonin Chambolle, Massimiliano Morini, Matteo Novaga +1
An existence and uniqueness result, up to fattening, for crystalline mean curvature flows with forcing and arbitrary (convex) mobilities, is proven. This is achieved by introducing…
