Abstract

In this paper we study the problems of existence and uniqueness of solution to the nonlinear multiparameter problems of the form
Au + 2]1 J B.0 = f,
j= J
where A, B.: X--X are mappings from a reflexive Banach space X into its dual space X , satisfying certain monotonicity corications,fEXIand),,.(j=1,21...,n) are in general complex parameters.
