Economic Equilibrium Theorems of Shafer-Sonnenschein Version and Nonempty Intersection Theorems in Interval Spaces

In this paper some equilibrium existence theorems for an abstract economy (or generalized game) of Shafer-Sonnenschein version and some nonempty interaction theorems for sets with W-convex sections in interval spaces are obtained. The results presented in this paper all are new and they are comparable to corresponding results in the relevant literature.
