On Differential Systems in Sobolev spaces with Generic Inhomogeneous Boundary Conditions

Abstract

We study linear systems of ordinary differential equations of an arbitrary order on a finite interval with the most general (generic) inhomogeneous boundary conditions in Sobolev spaces. We investigate the character of solvability of inhomogeneous boundary-value problems, prove their Fredholm properties, and find the indices, the dimensions of the kernel, and the cokernel of these problems. Moreover, we obtained necessary and sufficient conditions for continuity in a parameter of solutions to the introduced problems in Sobolev spaces.
