Continuity of some non-local functionals with respect to a convergence of the underlying measures

Abstract

We study some non-local functionals on the Sobolev space $W_0^{1,p}(\Omega )$ involving a double integral on $\Omega \times \Omega$ with respect to a measure $\mu$. We introduce a suitable notion of convergence of measures on product spaces which implies a stability property in the sense of $\Gamma$-convergence of the corresponding functionals.
