Convexity, Markov Operators, Approximation, and Related Optimization
Mathematics, 2022 The present review paper provides recent results on convexity and its applications to the constrained extension of linear operators, motivated by the existence of subgradients of continuous convex operators, the Markov moment problem and related Markov ...

On Markov Moment Problem, Polynomial Approximation on Unbounded Subsets, and Mazur–Orlicz Theorem [PDF]
Symmetry, 2021 We review earlier and recent results on the Markov moment problem and related polynomial approximation on unbounded subsets. Such results allow proving the existence and uniqueness of the solutions for some Markov moment problems. This is the first aim of the paper.

Applied General Topology, 2019 A ballean (or coarse space) is a set endowed with a coarse structure. A ballean X is called normal if any two asymptotically disjoint subsets of X are asymptotically separated.

Three Representations for Set Partitions
IEEE Access, 2021 The Set Partitioning Problem (SPP) aims to obtain non-empty disjoint subsets of objects such that their union equals the whole set of objects, and the partition meets some prespecified criteria.

The structure of normal subsets of polyhedral cone
Қарағанды университетінің хабаршысы. Математика сериясы, 2017 The structure of normal convex subsets of polyhedral cone K in normalized space is in investigated. The normality of the subset Ω ⊂ K (in the sense of the cone K) is determined by the condition Ω - K ∩K = Ω (a line over a set means taking a topological ...

International Mathematics Research Notices, 2022 AbstractFor a group $G$ let $\gamma ^{\max }_G(n)$ denote the maximum number of length-$n$ words over an arbitrary $n$-letter subset of $G$. If $G$ is finitely generated and residually finite, then either $\gamma ^{\max }_G(n)$ is exponentially bounded, if and only if $G$ is virtually abelian, or $\gamma ^{\max }_G(n)\geq ~\left (e^{-\frac {1}{4}}+o(1)\

Frames of multi-windowed exponentials on subsets of ${\mathbb R}^d$ [PDF]
, 2013 Given discrete subsets $\Lambda_j\subset {\Bbb R}^d$, $j=1,...,q$, consider the set of windowed exponentials $\bigcup_{j=1}^{q}\{g_j(x)e^{2\pi i }: \lambda\in\Lambda_j\}$ on $L^2(\Omega)$. We show that a necessary and sufficient condition for the windows

On Hahn-Banach theorem and some of its applications
Open Mathematics, 2022 First, this work provides an overview of some of the Hahn-Banach type theorems. Of note, some of these extension results for linear operators found recent applications to isotonicity of convex operators on a convex cone.

Mixed-integer convex representability [PDF]
, 2019 Motivated by recent advances in solution methods for mixed-integer convex optimization (MICP), we study the fundamental and open question of which sets can be represented exactly as feasible regions of MICP problems.
