Title: A viability result for second-order differential inclusions

Author: Vasile Lupulescu (Univ. Constantin Brancusi of Targu-Jiu, Romania)
         
Abstract: 
  We prove a viability result for the second-order differential inclusion 
  $$
  x''\in F(x,x'),\quad (x(0), x'(0))=(x_0,y_0)\in Q:=K\times \Omega, 
  $$
  where $K$ is a closed and $\Omega$ is an open subsets of $\mathbb{R}^m$,
  and is an upper semicontinuous set-valued map with compact values,  
  such that 
  $F(x,y) \subset \partial V(y)$, 
  for some convex proper  lower semicontinuous function $V$.
