Abstract

We prove the existence of solutions for some integro-differential systems containing equations with and without the drift terms in the H² spaces by virtue of the fixed point technique when the elliptic equations contain second order differential operators with and without the Fredholm property, on the whole real line or on a finite interval with periodic boundary conditions. Let us emphasize that the study of the systems case is more complicated than of the scalar situation and requires to overcome more cumbersome technicalities.
