Uniformly convex-transitive function spaces [PDF]
arXiv, 2009 We introduce a property of Banach spaces called uniform convex-transitivity, which falls between almost transitivity and convex-transitivity. We will provide examples of uniformly convex-transitive spaces. This property behaves nicely in connection with some Banach-valued function spaces.

International Journal for Numerical Methods in Engineering, Volume 126, Issue 3, 15 February 2025.ABSTRACT Porous microstructures represent a challenge for the convergence of FFT‐based computational homogenization methods. In this contribution, we show that the damped Eyre–Milton iteration is linearly convergent for a class of nonlinear composites with a regular set of pores, provided the damping factor is chosen between zero and unity.

Lipschitz‐free spaces over strongly countable‐dimensional spaces and approximation properties
Bulletin of the London Mathematical Society, Volume 57, Issue 2, Page 359-376, February 2025.Abstract Let T$T$ be a compact, metrisable and strongly countable‐dimensional topological space. Let MT$\mathcal {M}^T$ be the set of all metrics d$d$ on T$T$ compatible with its topology, and equip MT$\mathcal {M}^T$ with the topology of uniform convergence, where the metrics are regarded as functions on T2$T^2$. We prove that the set AT,1$\mathcal {A}

Random Structures &Algorithms, Volume 66, Issue 1, January 2025.Abstract The entropic doubling σent[X]$$ {\sigma}_{\mathrm{ent}}\left[X\right] $$ of a random variable X$$ X $$ taking values in an abelian group G$$ G $$ is a variant of the notion of the doubling constant σ[A]$$ \sigma \left[A\right] $$ of a finite subset A$$ A $$ of G$$ G $$, but it enjoys somewhat better properties; for instance, it contracts upon ...

Approximating fixed points of nonexpansive type mappings
International Journal of Mathematics and Mathematical Sciences, 2001 In a uniformly convex Banach space, the convergence of Ishikawa iterates to a unique fixed point is proved for nonexpansive type mappings under certain conditions.

Abstract and Applied Analysis, 2020 We prove Browder’s convergence theorem for multivalued mappings in a uniformly convex Banach space with a uniformly Gâteaux differentiable norm by using the notion of diametrically regular mappings.

Remarks on coarse embeddings of metric spaces into uniformly convex Banach spaces
Journal of Mathematical Analysis and Applications, 2006 AbstractWe study the support and convergence conditions for a metric space to be coarsely embeddable into a uniformly convex Banach space. By using ultraproducts we also show that the coarse embeddability of a metric space into a uniformly convex Banach space is determined by its finite subspaces.

The devil's staircase for chip‐firing on random graphs and on graphons
Random Structures &Algorithms, Volume 66, Issue 1, January 2025.Abstract We study the behavior of the activity of the parallel chip‐firing upon increasing the number of chips on an Erdős–Rényi random graph. We show that in various situations the resulting activity diagrams converge to a devil's staircase as we increase the number of vertices.

Abstract and Applied Analysis, 2011 We study weak convergence of the projection type Ishikawa iteration scheme for two asymptotically nonexpansive nonself-mappings in a real uniformly convex Banach space E which has a Fréchet differentiable norm or its dual E* has the Kadec-Klee property ...
