Existence and density results for retarded subdifferential evolution inclusions

Tiziana Cardinali, Simona Pieri (1996)

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

Similarity:

In this paper we study Cauchy problems for retarded evolution inclusions, where the Fréchet subdifferential of a function F:Ω→R∪{+∞} (Ω is an open subset of a real separable Hilbert space) having a φ-monotone subdifferential of oder two is present. First we establish the existence of extremal trajectories and we show that the set of these trajectories is dense in the solution set of the original convex problem for the norm topology of the Banach space C([-r, T₀], Ω) ("strong relaxation...

Existence and relaxation results for nonlinear second order evolution inclusions

Stanisław Migórski (1995)

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

Similarity:

In this paper we study nonlinear evolution inclusions associated with second order equations defined on an evolution triple. We prove two existence theorems for the cases where the orientor field is convex valued and nonconvex valued, respectively. We show that when the orientor field is Lipschitzean, then the set of solutions of the nonconvex problem is dense in the set of solutions of the convexified problem.
