Attempts to Approximate a Set-Valued Mapping

, 1985
Given a multi-valued mapping F, we address the problem of finding another multi-valued mapping H that agrees locally with F in some sense. We show that, contrary to the scalar case, introducing a derivative of F is hardly convenient. For the case when F is convex-compact-valued, we give some possible approximations, and at the same time we show their ...

Weak Subdifferentials for Set-Valued Mappings

Journal of Optimization Theory and Applications, 2013
The authors investigate the weak subdifferential for set-valued mappings, which was originally introduced by \textit{G. Y. Chen} and \textit{J. Jahn} [Math. Methods Oper. Res. 48, No. 2, 187--200 (1998; Zbl 0927.90095)]. After giving some preliminaries in Section 2, two existence theorems of weak subgradients for set-valued mappings are proven in ...

Set-Valued Mappings

2014
Chapter 9 is devoted to set-valued mappings. We study approximate fixed points of such mappings, existence of fixed points, and the convergence and stability of iterates of set-valued mappings. In particular, we consider a complete metric space of nonexpansive set-valued mappings acting on a closed and convex subset of a Banach space with a nonempty ...

On continuity of set-valued mappings

Topology and its Applications, 2022
The main results concern conditions on a topological space \(Y\) under which for a topological (possibly Baire) space \(X\) every upper or lower, or upper and lower quasi-continuous nonempty compact-valued mapping \(F:X\to K(Y)\) is upper or lower semi-countinuous at points of a residual subset of \(X\).
