Note on pointwise contractive projections
International Journal of Mathematics and Mathematical Sciences, 1993 Let C(X) be the space of real-valued continuous functions on a Hausdorff completely regular topological space X. endowed with the compact-open topology. In this paper necessary and sufficient conditions are given for a subspace of C(X) to be the range of

On the Generalization of a Class of Harmonic Univalent Functions Defined by Differential Operator
Mathematics, 2018 In this article, a new class of harmonic univalent functions, defined by the differential operator, is introduced. Some geometric properties, like, coefficient estimates, extreme points, convex combination and convolution (Hadamard product) are obtained.

Proceedings of the American Mathematical Society, 2000 Summary: Each weak\(^*\) compact \(C^*\)-convex set in a hyperfinite factor (in particular in \(B({\mathcal H})\)) is the weak\(^*\) closure of the \(C^*\)-convex hull of its \(C^*\)-extreme points.

Harmonic functions with varying coefficients
Journal of Inequalities and Applications, 2016 Complex-valued harmonic functions that are univalent and sense preserving in the open unit disk can be written in the form f = h + g ‾ $f=h+\overline{g}$ , where h and g are analytic.

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.

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].

New Rotation Sets in a Family of Torus Homeomorphisms [PDF]
, 2015 We construct a family $\{\Phi_t\}_{t\in[0,1]}$ of homeomorphisms of the two-torus isotopic to the identity, for which all of the rotation sets $\rho(\Phi_t)$ can be described explicitly.

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.

Deep Extreme Cut: From Extreme Points to Object Segmentation
, 2018 This paper explores the use of extreme points in an object (left-most, right-most, top, bottom pixels) as input to obtain precise object segmentation for images and videos.

Structure of Extreme Correlated Equilibria: a Zero-Sum Example and its Implications [PDF]
, 2010 We exhibit the rich structure of the set of correlated equilibria by analyzing the simplest of polynomial games: the mixed extension of matching pennies.
