Definable Lipschitz selections for affine-set valued maps

Israel Journal of Mathematics, 2023
Whitney's extension problem, i.e., how one can tell whether a function $f : X \to \mathbb R$, $X \subseteq \mathbb R^n$, is the restriction of a $C^m$-function on $\mathbb R^n$, was solved in full generality by Charles Fefferman in 2006.

On Constructive Extractability of Measurable Selectors of Set-Valued Maps

IEEE Transactions on Automatic Control, 2021
This article investigates the possibility of constructive extraction of measurable selector from set-valued maps, which may commonly arise in viability theory, optimal control, discontinuous systems, etc.

Continuation theorems for Mƶnch countable compactness-type set-valued maps

Applicable Analysis, 2019
A number of Leray–Schauder-type continuation theorems for general classes of maps are presented in this paper. Our maps will satisfy a countable compactness-type condition.
