In this paper we discuss the weak type(H^p,L^p) boundedness of a class of maximal operators T*^ψ and themaximal strong mean boundedness of a family of the oper
A associative ring R with an unit element is called an Ivolutive RIng,if every element of the muttiplicative group U/(R),which consists of all the units of R,sa
In this paper,applying the concept of generalized KKM map,we study problems of variational inequalities.We weaken convexity(concavity) conditions for a function
