Positive weighted koopman semigroups on banach lattice modules [PDF]

, 2023
Thesis (MSc)--Stellenbosch University, 2023.ENGLISH SUMMARY: In this thesis, we introduce the notion of a positive weighted semigroup representation on a Banach lattice module over a group representation on a commutative Banach lattice algebra.

Multiple front and pulse solutions in spatially periodic systems

Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract In this paper, we develop a comprehensive mathematical toolbox for the construction and spectral stability analysis of stationary multiple front and pulse solutions to general semilinear evolution problems on the real line with spatially periodic coefficients.

An absolute continuity for positive operators on Banach lattices

International Journal of Mathematics and Mathematical Sciences, 1991
For positive operators on a Banach lattice, absolute contnuity conditions are considered. An operator absolutely continuous with respect to T is compared to sums of compositions of T together with orthomorphisms or in special cases projections ...

On limited and almost limited operators between Banach lattice

Қарағанды университетінің хабаршысы. Математика сериясы
This article investigates theoretical questions concerning the class of (almost) limited operators on Banach lattices, focusing on their precise relations to L-weakly compact, semi-compact, and Dunford–Pettis operators.

The Köthe Dual of an Abstract Banach Lattice

Journal of Function Spaces and Applications, 2013
We analyze a suitable definition of Köthe dual for spaces of integrable functions with respect to vector measures defined on δ-rings. This family represents a broad class of Banach lattices, and nowadays it seems to be the biggest class of spaces ...

Unitarily invariant valuations on convex functions

Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract Continuous, dually epi‐translation invariant valuations on the space of finite‐valued convex functions on Cn$\mathbb {C}^n$ that are invariant under the unitary group are investigated. It is shown that elements belonging to the dense subspace of smooth valuations admit a unique integral representation in terms of two families of Monge–Ampère ...

The class of Banach lattices is not primary

Forum of Mathematics, Sigma
Building on a recent construction of Plebanek and Salguero-Alarcón, which solved the Complemented Subspace Problem for $C(K)$ -spaces, and the subsequent work of De Hevia, Martínez-Cervantes, Salguero-Alarcón, and Tradacete solving the Complemented

The lattice copies of $\ell_1$ in Banach lattices

, 2001
summary:It is known that a Banach lattice with order continuous norm contains a copy of $\ell_1$ if and only if it contains a lattice copy of $\ell_1$.
