On Directionally Dependent Subdifferentials

چکیده
In this paper directionally contextual concepts of variational analysis, based on dual-~pace cou-siructions similar to those in [4, 5], are introduced and studied. As an illustration of their usefulnes~, necessary and ft!so sufficient optimality conditions in terms of directioual subdiffeJ • ent.ials are established , and it is shown that they can be effective in the situations where known optimality conditions iu tenus of uondirectiona.l Stibclifferent.ials fail.

Integrability of Subdifferentials of Directionally Lipschitz Functions
Using a quantitative version of the subdifferential characterization of directionally Lipschitz functions, we study the integrability of subdifferentials of such functions over arbitrary Banach space.

Subdifferentials of convex functions and some regular functions f are expressed in terms of limiting gradients at points in a given dense subset of dorn Vf.
متن کاملAttractors for Nonautonomous Multivalued Evolution Systems Generated by Time-dependent Subdifferentials
In a real separable Hilbert space, we consider nonautonomous evolution equations including time-dependent subdifferentials and their nonmonotone multivalued perturbations. In this paper, we treat the multivalued dynamical systems associated with time-dependent subdifferentials, in which the solution is not unique for a given initial state. In particular, we discuss the asymptotic behaviour of o...
متن کاملPartial second-order subdifferentials of -prox-regular functions
Although prox-regular functions in general are nonconvex, they possess properties that one would expect to find in convex or lowerC2 functions. The class of prox-regular functions covers all convex functions, lower C2 functions and strongly amenable functions. At first, these functions have been identified in finite dimension using proximal subdifferential. Then, the definition of prox-regula...
متن کاملLimiting subdifferentials of perturbed distance functions in Banach spaces
We explore in arbitrary Banach spaces the Fréchet type ε-subdifferentials and the limiting subdifferentials for the perturbed distance function dS(·) determined by a closed subset S and a lower semicontinuous function J defined on S. In particular, upper and lower estimates for the Fréchet type ε-subdifferentials and for the limiting subdifferentials are provided in terms of the corresponding s...
