We prove theorems on the character of solvability and regularity of solutions of general elliptic boundary-value problems in Hilbert Hörmander spaces modified by Roitberg. An arbitrary real number and a sufficiently general weight function of frequency variables serve as the indices of regularity for these spaces.
