Abstract. In the article we consider the  Sturm-Liouville operator with semiseparated boundary conditions, one of which contains a spectral parameter. An asymptotic formula for the eigenvalues of the operator under consideration is given and a uniqueness theorem for the solution of the inverse problem of recovering the corresponding boundary value problems is proved.

Keywords: Sturm-Liouville operator, eigenvalues, inverse problem, uniqueness theorem

Abstract. The problem of a longitudinal impact on a piecewise homogeneous semi-infinite rod consisting of viscoelastic parts is studied. Introducing non-stationary dynamic regularization under conjugation conditions, we prove the well-posedness of the problem under consideration
