Journal of Convex Analysis 10 (2003), No. 2, 365--378 Copyright Heldermann Verlag 2003 Existence in Optimal Control with State Equation in Divergence Form via Variational Principles José Carlos Bellido ETSI Industriales, Universidad de Castilla-La Mancha, 13071 Cuidad Real, Spain Pablo Pedregal ETSI Industriales, Universidad de Castilla-La Mancha, 13071 Cuidad Real, Spain We explore several relevant issues concerned with some typical two-dimensional optimal design problems by using a purely variational format. Specifically, we investigate situations of existence of optimal solutions and relaxation in terms of quasiconvexifications and Young measures. Keywords: Variational framework, existence-nonexistence of optimal solutions, relaxation, Young measures. MSC 1991: 49J15, 49J45, 74P10. FullText-pdf (300 K) |
