Equilibria and strict equilibria of multivalued maps on noninvariant sets
Pierre Cardaliaguet, Grzegorz Gabor, Marc Quincampoix · Annales Polonici Mathematici · 2003
This paper is concerned with existence of equilibrium of a set-valued map in a given compact subset of a finite-dimensional space. Previously known conditions ensuring existence of equilibrium imply that the set is either invariant or viable for the diffe
