In this paper, we present a KKM type theorem, some coincidence theorems in FC -spaces and a collective fixed-point theorem for a family of set-valued mappings defined on the product space of locally FC -spaces. As applications, some intersection theorems and minimax theorems are proved. Our results

β¦ Synopsis
By using a continuous selection theorem, some new collective fixed point theorems and coincidence theorems for the families of set-valued mappings defined on the product space of noncompact FC-spaces are proved under very weak assumptions. As applications, some nonempty intersection theorems, inclusion theorems and existence theorems of solutions for systems of inequalities are established in the product space of noncompact FC-spaces. These results generalize many known results from the recent literature.

The notion of a βΏ, C -contraction type multivalued mapping is introduced. This notion is a generalization of the notion of C-contraction introduced by T. L. Hicks Ε½ .
In this paper, we study a class of nonlinear operator equations with more extensive conditions in ordered Banach spaces. By using the cone theory and Banach contraction mapping principle, the existence and uniqueness of solutions for such equations are investigated without demanding the existence of
