Abstract

The Lipschitz-like property relative to a set is important in applications. In this talk we introduce a projectional coderivative of set-valued mappings and present its calculations in some special cases. We apply this coderivative to obtain a complete characterization for a set-valued mapping to have the Lipschitz-property relative to a closed and convex set. For an extended real-valued function, we apply the obtained results to investigate its Lipschitz continuity relative to a closed and convex set and the Lipschitz-like property of a level-set mapping relative to a half line. We apply our results to study the Lipschitz-like property of the solution mapping of a parametric affine variational inequality problem.
