A Detailed Study of ABC‐Type Fractal–Fractional Dynamical Model of HIV/AIDS
Computational and Mathematical Methods, Volume 2025, Issue 1, 2025.This paper is aimed at studying the dynamics of community transmission of HIV by constructing a fractal fractional mathematical model whose kernel is a generalized Mittag–Leffler type. First, we collect and analyze statistical data for epidemiological surveillance of HIV/AIDS prevalence in Yemen from 2000 to 2022.

A Note on the class of superreflexive almost transitive Banach spaces [PDF]
arXiv, 2008 The class J of simultaneously almost transitive, uniformly convex and uniformly smooth Banach spaces is characterized in terms of convex-transitivity and weak geometry of the norm.

k-β and k-nearly uniformly convex Banach spaces
Journal of Mathematical Analysis and Applications, 1991 vol. 162, No. 2, 1991 k-β and k-Nearly Uniformly Convex Banach Spaces Denka Kutzarova Different uniform geometrical properties have been defined between the uniform convexity and the reflexivity of Banach spaces. In the present paper we introduce other properties of this type, namely k-β and k-nearly uniform convexity.

On sets minimizing their weighted length in uniformly convex separable Banach spaces [PDF]
arXiv, 2013 We study existence and partial regularity relative to the weighted Steiner problem in Banach spaces. We show $C^1$ regularity almost everywhere for almost minimizing sets in uniformly rotund Banach spaces whose modulus of uniform convexity verifies a Dini growth condition.

Continuity of metric projections in uniformly convex and uniformly smooth Banach spaces
Journal of Approximation Theory, 1983 AbstractThe continuity of the metric projection onto an approximatively compact set in a uniformly convex and uniformly smooth Banach space is investigated. An explicit modulus of continuity for the metric projection which depends on the directional radius of curvature at a certain point of the set is obtained.

Characterization of uniformly convex and smooth Banach spaces by using Carleson measures in Bessel settings [PDF]
, 2011 In this paper we obtain new characterizations of the q-uniformly convex and smooth Banach spaces by using Carleson measures. These measures are defined by Poisson integral associated with Bessel operators and Banach valued BMO-functions.

The alternating algorithm in a uniformly convex and uniformly smooth Banach space
Journal of Mathematical Analysis and Applications, 2015 Abstract Let X be a uniformly convex and uniformly smooth Banach space. Assume that the M i , i = 1 , … , r , are closed linear subspaces of X, P M i is the best approximation operator to the linear subspace M i , and M : = M 1 + ⋯ + M r .

Mordukhovich derivatives of the normalized duality mapping in Banach spaces [PDF]
arXivIn this paper, we investigate some properties of the Mordukhovich derivatives of the normalized duality mapping in Banach spaces. For the underlying spaces, we consider three cases: uniformly convex and uniformly smooth Banach space lp; general Banach spaces L1 and C[0,1].
