Monotone gradients on Banach lattices [PDF]

open access: yesProceedings of the American Mathematical Society, 1986
It is well known that a differentiable real valued function on the real line is convex iff its derivative is nondecreasing. This characterization of differentiable convex functions does not extend if the domain of the function is a Banach lattice of dim ⩾ 2 \dim \geqslant 2 .

Lipschitz decompositions of domains with bilaterally flat boundaries

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 3, March 2025.
Abstract We study classes of domains in Rd+1,d⩾2$\mathbb {R}^{d+1},\ d \geqslant 2$ with sufficiently flat boundaries that admit a decomposition or covering of bounded overlap by Lipschitz graph domains with controlled total surface area. This study is motivated by the following result proved by Peter Jones as a piece of his proof of the Analyst's ...

Asymptotics of block Toeplitz determinants with piecewise continuous symbols

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 1, Page 120-160, January 2025.
Abstract We determine the asymptotics of the block Toeplitz determinants detTn(ϕ)$\det T_n(\phi)$ as n→∞$n\rightarrow \infty$ for N×N$N\times N$ matrix‐valued piecewise continuous functions ϕ$\phi$ with a finitely many jumps under mild additional conditions.

Sumsets and entropy revisited

open access: yesRandom 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 ...

Ergodic Banach lattices

open access: yesIndagationes Mathematicae, 1990
An operator T on a Banach space E is said to be ergodic, provided the averages 1/n\(\sum^{bn-1}_{k=0}T^ kx\) converge in norm for each \(x\in E.\) Assume that E is a Banach lattice satisfying either of the following two conditions: (i) E is Dedekind \(\sigma\)-complete, or (ii) E has a topological orthogonal system.

Asymptotic analysis of a coupled ODE‐PDE system arising from heterogeneous diffusion‐reaction kinetics

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 105, Issue 1, January 2025.
Abstract This contribution is concerned with the well‐posedness and homogenization of an ordinary differential equation (ODE) of Arrhenius‐type coupled with a doubly nonlinear parabolic partial differential equation (PDE) with rapidly oscillating coefficients and taking into account disparate diffusion‐reaction time scales, including regularly as well ...

Characterization of Best Approximation Points with Lattice Homomorphisms

open access: yesJournal of Mathematical Extension, 2014
In this paper we prove some characterization theorems in the theory of best approximation in Banach lattices. We use a new idea for finding the best approximation points in an ideal.

A Note on Spectral Sublinearity for Collections of Positive Compact Operators on Banach Lattices

open access: yesSpecial Matrices, 2018
In this paper we consider the question when a triangularizable semigroup S of positive compact ideal-triangularizable operators on an order continuous Banach lattice X is ideal-triangularizable.
