In this paper, by virtue of the separation theorem of convex sets, we prove a minimax
theorem, a cone saddle point theorem and a Ky Fan minimax theorem for a scalar set …

In this paper, we introduce and study a generalized strongly vector equilibrium problem for
set-valued map**s in real Banach spaces. Using Minty type lemma and KKM-Fan theorem …

In this paper, several kinds of generalized vector quasi-equilibrium problems are introduced
and studied in abstract convex spaces. Using the properties of Γ-convex and KC KC-maps …

In this paper, we introduce a class of set-valued map**s with some set order relations,
which is called uniformly same-order. For this sort of map**s, we obtain some existence …

In this paper, a class of set-valued map**s is introduced, which is called uniformly same-
order. For this sort of map**s, some minimax problems, in which the minimization and the …

This is to give a short history of our multimap classes K, KC, KO in the KKM theory. We show
that many authors adopted or imitated the inadequate definition of the KKM class due to …

In this paper, we introduce and study a class of generalized symmetric vector quasi-
equilibrium problems in abstract convex spaces. By virtue of the properties of Γ-convex and …
