Petkov, Vesselin M. Diffusion phase for some restricted perturbations. (Phase de diffusion pour des perturbations captives.) (French) Zbl 0718.35007 Journ. Équ. Dériv. Partielles, St.-Jean-De-Monts 1990, No. 5, 10 p. (1990). This brief note studies the diffusive behaviour of certain perturbations of the diffusion equation in \(R^ n\), with \(n\geq 3\). A general theorem is proved and a connection established with the Schrödinger operator.
