Existence and controllability for stochastic evolution inclusions of Clarke's subdifferential type [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, we investigate a class of stochastic evolution inclusions of Clarke's subdifferential type in Hilbert spaces. The existence of mild solutions and controllability results are given and proved by using stochastic analysis techniques ...

Lipschitz functions with maximal Clarke subdifferentials are generic [PDF]

open access: yesProceedings of the American Mathematical Society, 2000
We show that on a separable Banach space most Lipschitz functions have maximal Clarke subdifferential mappings. In particular, the generic nonexpansive function has the dual unit ball as its Clarke subdifferential at every point. Diverse corollaries are given.

Existence trajectory and optimal control of Clarke subdifferential stochastic integrodifferential inclusions suffered by non-instantaneous impulses and deviated arguments

open access: yesResults in Control and Optimization, 2023
In this article, the solvability, Trajectory(T-) and optimal controllability of stochastic integrodifferential inclusions with Clarke subdifferential along with deviated arguments and Poisson jumps are analyzed which are new and untreated topics in the ...

On generalized derivatives for C1,1 vector optimization problems

open access: yesJournal of Applied Mathematics, 2003
We introduce generalized definitions of Peano and Riemann directional derivatives in order to obtain second-order optimality conditions for vector optimization problems involving C1,1 data.
