The approximate variation of univariate uniform space valued functions and pointwise selection principles

Vyacheslav V. Chistyakov, Svetlana A. Chistyakova

Let $T \subset R$ and $(X, U)$ be a uniform space with an at most countable gage of pseudometrics ${d_{p} : p \in P}$ of the uniformity $U$ . Given $…

Asymmetric variations of multifunctions with application to functional inclusions

Vyacheslav V. Chistyakov

Under certain initial conditions, we prove the existence of set-valued selectors of univariate compact-valued multifunctions of bounded (Jordan) variation when the notion of variat…
