  • Anti-periodic solutions for nonlinear evolution inclusions
    Gasiński, Leszek ; Papageorgiou, Nikolaos, 1958-
    We consider an anti-periodic evolution inclusion defined on an evolution triple of spaces, driven by an operator of monotone-type and with a multivalued reaction term ▫$F(t, x)$▫. We prove existence ... theorem for the "convex" problem (that is, ▫$F$▫ is convex-valued) and for the "nonconvex" problem (that is, ▫$F$▫ is nonconvex-valued) and we also show the existence of extremal trajectories (that is, when ▫$F$▫ is replaced by ▫$\text{ext}F$▫). Finally, we prove a "strong relaxation" theorem, showing that the extremal trajectories are dense in the set of solutions of the convex problems.
