Contact-boundary value problem in the non-classical treatment for one   pseudoparabolic equation
  In the paper, the contact - boundary value problem with non-classical conditions not requiring agreement conditions is considered for a pseudoparabolic equation. The equivalence of these conditions is substantiated in the case if the solution of the solution of the stated problem is sought in S.L.Sobolev isotropic space.
