On compact perturbations and compact resolvents of nonlinear 𝑚-accretive operators in Banach spaces
Athanassios G. Kartsatos · Proceedings of the American Mathematical Society · 1993
Several mapping results are given involving compact perturbations and compact resolvents of accretive and m-accretive operators. A simple and straightforward proof is given to an important special case of a result of Morales who has recently improved and/or extended various results by the author and Hirano. Improved versions of results of Browder and Morales are shown to be possible by studying various homotopies of compact transformations.
