Viscosity coderivatives and their limiting behavior in smooth spaces

B. S. Mordukhovich, Y. Shao and Q. J. Zhu

Abstract: This paper concerns with generalized differentiation of set-valued and nonsmooth mappings between bornological Banach spaces. We study the so-called viscosity coderivatives of multifunctions and their limiting behavior under certain geometric assumptions on spaces in question related to the existence of smooth bump functions of any kind. The main results include various calculus rules for viscosity coderivatives and their topological limits. They are important in applications to variational analysis and optimization.
