## Abstract In this paper we study a class of elliptic secondβorder differential operators on finite dimensional convex compact sets whose principal part degenerates on a subset of the boundary of the domain. We show that the closures of these operators generate Feller semigroups. Moreover, we app

## Abstract We study the tensionβcompression vibration of an elastic cusped plate under (all reasonable) boundary conditions at the cusped edge and given displacements at the nonβcusped edge and stresses at the upper and lower faces of the plate. (Β© 2007 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
A degenerate, doubly nonlinear parabolic system is approximated by a nondegenerate one. The proposed type of approximation is effective from numerical point of view. The convergence of approximate solutions is proved for a rather general mathematical model.
