Popis
Shrnutí:This paper introduces and considers the concept of generalized subsmoothness of a multifunction, which is a generalization of both the prox-regularity property and the subsmoothness property of multifunctions. Subsequently, it mainly deals with generalized metric subregularity (in particular, Hölder metric subregularity) for general set-valued mappings in Asplund spaces. Employing advanced techniques of variational analysis and generalized differentiation, we derive sufficient conditions for generalized metric subregularity, which extend even the known results for the conventional metric subregularity. In particular, our results improve/extend the main results established by Li and Mordukhovich (SIAM J. Optim. 22:1655–1684, 2012 ). Moreover, we also conduct local convergence analysis of an inexact quasi-Newton method for solving the generalized equation 0 ∈ f ( x ) + F ( x ) in Banach spaces, where the function f is continuous but not smooth and F is a set-valued mapping with closed graph.
