Some new generalized G-KKM and generalized S-KKM theorems are proved under the noncompact setting of generalized convex spaces. As applications, some new minimax inequalities, saddle point theorems, a coincidence theorem, and a fixed point theorem are given in generalized convex spaces. These theore

โฆ Synopsis
This paper deals with some new generalizations of Farkas' theorem for a class of set-valued mappings with arbitrary convex cones in infinite-dimensional Banach spaces. A modified Farkas' theorem with no closedness assumption is given. The generalized Gale alternative theorem in nonlinear programming is derived as an easy consequence. The results are applied to constrained controllability theory in Banach spaces as well as to some multiobjective optimization problem. แฎ 1997

The fuzzy controllers studied in this paper have r input variables (error, rate change of error of process output, etc.). N members of input fuzzy sets are employed to fuzzify the inputs. N" nonlinear control rules represented by an arbitrary function f are used, which are evaluated by any type of f
