Regularity of stable interfaces: from nonlocal to local
Serra, Joaquim (2019-11-21)
Audiovisual
Accés obertI will describe recent results with Alessio Figalli on 1D symmetry of stable critical points of the Ginzburg-Landau functional associated to the half-Laplacian. As we will discuss, an interesting feature of these ... -

Sharp isoperimetric inequalities via the ABP
Cabré Vilagut, Xavier; Ros-Oton, Xavier; Serra, Joaquim (2016-01-01)
Article
Accés obertGiven an arbitrary convex cone of Rn, we find a geometric class of homogeneous weights for which balls centered at the origin and intersected with the cone are minimizers of the weighted isoperimetric problem in the convex ... -
Stable s-minimal cones in R 3 are flat for s ~ 1
Cabré Vilagut, Xavier; Cinti, Eleonora; Serra, Joaquim (2019-01-01)
Article
Accés obertWe prove that half spaces are the only stable nonlocal s-minimal cones in R3, for s¿(0,1) sufficiently close to 1. This is the first classification result of stable s-minimal cones in dimension higher than two. Its proof ... -
Stable solutions to semilinear elliptic equations are smooth up to dimension 9
Cabré Vilagut, Xavier; Figalli, Alessio; Ros Oton, Xavier; Serra, Joaquim (2020-01-01)
Article
Accés obertIn this paper we prove the following long-standing conjecture: stable solutions to semi-linear elliptic equations are bounded (and thus smooth) in dimension n¿9. This result, that was only known to be true for n¿4 , is ...
