Degree of mapping for nonlinear mappings of monotone type: Densely defined mapping
Felix E. Browder · Proceedings of the National Academy of Sciences · 1983
The classical degree function constructed earlier for pseudomonotone mappings has been used to develop a broader degree theory of classical type for the sum of a maximal monotone map from a reflexive Banach space to its dual together with a bounded pseudomonotone map. The proof uses the generalized Yosida approximation of the maximal monotone mapping.
