Keywords:

Subject:
The homogenization of different boundary problems for elliptic scalar and vector operators (linear and nonlinear) in perforated domains was prooved. Among them there are problems with unilateral boundary condition, problems of porous media theory, elasticity theory problems on singular and thin structures. The well-posedness of hyperbolic boundary problems with oblique derivative was investigated.
