Abstract
Let be an infinite-dimensional real reflexive Banach space with dual space and open and bounded. Assume that and are locally uniformly convex. Let be maximal monotone and quasibounded and of type . Assume that , where is a dense subspace of , and . A new topological degree theory is introduced for the sum . Browder's degree theory has thus been extended to densely defined perturbations of maximal monotone operators while results of Browder and Hess have been extended to various classes of single-valued densely defined generalized pseudomonotone perturbations . Although the main results are of theoretical nature, possible applications of the new degree theory are given for several other theoretical problems in nonlinear functional analysis.
