Title: Uniqueness of critical points for semi-linear 
       Dirichlet problems in convex domains

Author: Jaime Arango (Univ. del Valle, Cali, Colombia)

Abstract: 
 We  establish sufficient conditions for the existence
 of a unique critical point for the solution to the 
 semi linear  elliptic problem $ \Delta u = f(u)+w $   
 with zero Dirichlet  boundary condition.
