Abstract

The autor considers an initial-boundary value problem for the nonstationary Stokes system in an angle, where Dirichlet and Neumann conditions are prescribed on the diferent sides of the angle. The major part of the paper deals with the parameter-depending problem which arises after the application of the Laplace transform. The author obtains existence, uniqueness and regularity results for this problem in a class of weighted Sobolev spaces. Using the properties of the Laplace transform, he proves the existence and uniqueness of strong solutions of the time-dependent problem.
