A unified representation of some starlike and convex harmonic functions with negative coefficients [PDF]
Opuscula Mathematica, 2013 In this paper we introduce a unified representation of starlike and convex harmonic functions with negative coefficients, related to uniformly starlike and uniformly convex analytic functions.

On the extreme points and strongly extreme points in Köther-Bochner spaces
Publications de l'Institut Mathematique, 2012 We give the necessary conditions of extreme points and strongly extreme points in the unit ball of K?the-Bochner spaces. The conditions have been shown to be sufficient earlier.

Extreme points of ${\mathcal L}_s(^2l_{\infty})$ and ${\mathcal P}(^2l_{\infty})$
Karpatsʹkì Matematičnì Publìkacìï, 2021 For $n\geq 2,$ we show that every extreme point of the unit ball of ${\mathcal L}_s(^2l_{\infty}^n)$ is extreme in ${\mathcal L}_s(^2l_{\infty}^{n+1})$, which answers the question in [Period. Math. Hungar. 2018, 77 (2), 274-290].

A short note on extreme points of certain polytopes
Special Matrices, 2020 We give a short proof of Mirsky’s result regarding the extreme points of the convex polytope of doubly substochastic matrices via Birkhoff’s Theorem and the doubly stochastic completion of doubly sub-stochastic matrices.

Проблемы анализа, 2023 With the aid of 𝑞-calculus, this paper introduces a new generalized p𝑝, 𝑞q-Bernardi integral operator ℬ^𝑝 𝑛,𝑞𝑓p𝑧q. Then, we define a new subclass of harmonic p𝑝, 𝑞q-starlike functions of complex order associated with the operator ℬ^𝑝 𝑛,𝑞𝑓p𝑧q.

Bohnenblust-Hille inequalities: analytical and computational aspects
Anais da Academia Brasileira de Ciências, 2018 The Bohnenblust-Hille polynomial and multilinear inequalities were proved in 1931 and the determination of exact values of their constants is still an open and challenging problem, pursued by various authors.

Classification of the extreme points of ${\mathcal L}_s(^2l_{\infty}^3)$ by computation
Karpatsʹkì Matematičnì Publìkacìï, 2022 Let $l_{\infty}^3=\mathbb{R}^3$ be endowed with the supremum norm. In [Comment. Math. 2017, 57 (1), 1-7], S.G. Kim classified the extreme points of the unit ball of ${\mathcal L}_s(^2l_{\infty}^3)$ only using Mathematica 8, where ${\mathcal L}_s(^2l_ ...

Harmonic Starlike Functions with Respect to Symmetric Points
Axioms, 2019 In the paper we define classes of harmonic starlike functions with respect to symmetric points and obtain some analytic conditions for these classes of functions.
