Abstract

In this work we analyze the behavior of the solutions to nonlocal evolution equations of the form ut(x,t)=J(xy)u(y,t)dyhϵ(x)u(x,t)+f(x,u(x,t))u_t(x,t) = \int J(x-y) u(y,t) \, dy - h_\epsilon(x) u(x,t) + f(x,u(x,t)) with xx in a perturbed domain ΩϵΩ\Omega^\epsilon \subset \Omega which is thought as a fixed set Ω\Omega from where we remove a subset AϵA^\epsilon called the holes. We choose an appropriated families of functions hϵLh_\epsilon \in L^\infty in order to deal with both Neumann and Dirichlet conditions in the holes setting a Dirichlet condition outside Ω\Omega. Moreover, we take JJ as a non-singular kernel and ff as a nonlocal nonlinearity. % Under the assumption that the characteristic functions of Ωϵ\Omega^\epsilon have a weak limit, we study the limit of the solutions providing a nonlocal homogenized equation.
