| Abstract: | We obtain some results on solvability of boundary value problems for the equation But–Lu =f (t (0, )), where B and L are selfadjoint and dissipative operators defined in a Hilbert space E. The kernel of B may be nontrivial and L is uniformly dissipative on a subspace M of finite codimension. |
