Equilibrium of permanent multivalued systems
Yong Li, Huai Zhong Wang, Xian Rui Lü · Quarterly of Applied Mathematics · 1993
This paper is concerned with the existence problem of an equilibrium state for permanent multivalued systems. It is proved that the permanence of multivalued systems implies the existence of an equilibrium state by using the approximating technique of set-valued maps and asymptotic fixed point theory.
