Abstract

We study the Γ\Gamma-convergence of the following functional (p>2p>2) Fϵ(u):=ϵp2ΩDupd(x,Ω)adx+1ϵp2p1ΩW(u)d(x,Ω)ap1dx+1ϵΩV(Tu)dH2, F_{\epsilon}(u):=\epsilon^{p-2}\int_{\Omega}|Du|^p d(x,\partial \Omega)^{a}dx+\frac{1}{\epsilon^{\frac{p-2}{p-1}}}\int_{\Omega}W(u) d(x,\partial \Omega)^{-\frac{a}{p-1}}dx+\frac{1}{\sqrt{\epsilon}}\int_{\partial\Omega}V(Tu)d\mathcal{H}^2, where Ω\Omega is an open bounded set of R3\mathbb{R}^3 and WW and VV are two non-negative continuous functions vanishing at α,β\alpha, \beta and α,β\alpha', \beta', respectively. In the previous functional, we fix a=2pa=2-p and uu is a scalar density function, TuTu denotes its trace on Ω\partial\Omega, d(x,Ω)d(x,\partial \Omega) stands for the distance function to the boundary \Om\partial\Om. We show that the singular limit of the energies FϵF_{\epsilon} leads to a coupled problem of bulk and surface phase transitions.
