Abstract : The paper is devoted to the diffusion equation with discrete absorption described by a sum of Dirac δ-functions. Their supports are located at the nodes of some regular grid with the distance between them determined by the integral of solution. This model describes contraction of biological tissue when cells consume some substance influencing their interaction. In the one-dimensional formulation we prove existence of solutions of the discrete problem and their convergence to the solution of the limiting homogenized problem.
