Abstract:  
   In this paper we investigate the existence of mild
   solutions to second order initial value problems for
   a class of damped differential inclusions with nonlocal
   conditions.  By using suitable fixed point theorems,
   we study the case when the multivalued map has convex
   and nonconvex values.
