IMPULSIVE BOUNDARY VALUE PROBLEMS FOR DYNAMICAL INCLUSIONS ON TIME SCALES

摘要

In this paper, the authors investigate the existence of solutions of impulsive boundary value problems for second-order ordinary differential inclusions which admitting non-convex valued on right-hand function Some new results under weaker conditions are exhibited. The methods rely on a fixed point theorem for contraction multivalued maps due to Covitz and Nadler and Schaefer's fixed point theorem combined with lower semi-continuous multivalued operators with decomposable values
