Elliptic Boundary-Value Problems in the Sense of Lawruk on Sobolev and Hörmander Spaces

We study elliptic boundary-value problems with additional unknown functions in boundary conditions. These problems were introduced by Lawruk. We prove that the operator corresponding to a problem of this kind is bounded and Fredholm in appropriate couples of the inner product isotropic Hörmander spa...
