Some applications of a fixed point theorem for multivalued mappings in topological vector spaces


Olga Hadžić




In [3] a fixed point theorem for multivalued mappings in not necessarily locally convex topological vector spaces is proved. Here we obtain, by using this fixed point theorem and the dual result, two theorems on the coincidence point, a result on the equilibrium state in a special noncooperative game and three existence theorems for some classes of equations.
