On the modulus of u-convexity of Ji Gao [PDF]
Abstract and Applied Analysis, 2003 We consider the modulus of u-convexity of a Banach space introduced by Ji Gao (1996) and we improve a sufficient condition for the fixed-point property (FPP) given by this author.

Modulus of Convexity, the Coeffcient R(1,X), and Normal Structure in Banach Spaces
Abstract and Applied Analysis, 2008 Let δX(ϵ) and R(1,X) be the modulus of convexity and the Domínguez-Benavides coefficient, respectively. According to these two geometric parameters, we obtain a sufficient condition for normal structure, that is, a Banach space X has normal structure if

Abstract and Applied Analysis, 2022 In this paper, we consider a JS metric space endowed with convexity structure, which will allow us to examine and study convergence of Mann iteration and Ishikawa iteration for Banach type and Chatterjea type contractions defined on JS metric space.

Convex structures revisited [PDF]
Ergodic Theory and Dynamical Systems, 2015 We provide a complete characterization of extreme points of the space of sofic representations. We also show that the restriction map $\text{Sof}(G,P^{{\it\omega}})$ to $\text{Sof}(H,P^{{\it\omega}})$, where $H\subset G$, is not always surjective. The first part of the paper is a continuation of Păunescu [A convex structure on sofic embeddings.

Modular Uniform Convexity in Every Direction in Lp(·) and Its Applications
Mathematics, 2020 We prove that the Lebesgue space of variable exponent L p ( · ) ( Ω ) is modularly uniformly convex in every direction provided the exponent p is finite a.e. and different from 1 a.e.

Quantiles in Abstract Convex Structures [PDF]
Axioms, 2018 In this short paper, we aim at a qualitative framework for modeling multivariate decision problems where each alternative is characterized by a set of properties. To this extent, we consider convex spaces as underlying universes and make use of lattice operations in convex spaces to formalize the notion of quantiles.

Trace-Inequalities and Matrix-Convex Functions
Fixed Point Theory and Applications, 2010 A real-valued continuous function f(t) on an interval (α,β) gives rise to a map X↦f(X) via functional calculus from the convex set of n×n Hermitian matrices all of whose eigenvalues belong to the interval. Since the subpace of

Variation in wing morphology is related to breeding environment in a high‐elevation specialist bird
Journal of Avian Biology, 2022 The morphology of bird wings is subject to a variety of selective pressures, including migration, predation, habitat structure and sexual selection.
