An Introduction to i-Commutative Rings

Mathematics
In this paper, we introduce a new class of rings, called i-commutative rings, by extending the concept of commutative-like rings using idempotent elements.

On the injective dimension of unit Cartier and unit Frobenius modules

Bulletin of the London Mathematical Society, EarlyView.
Abstract Let R$R$ be a regular F$F$‐finite ring of prime characteristic p$p$. We prove that the injective dimension of every unit Frobenius module M$M$ in the category of unit Frobenius modules is at most dim(SuppR(M))+1$\dim (\operatorname{Supp}_R(M))+1$.

Coloured shuffle compatibility, Hadamard products, and ask zeta functions

Bulletin of the London Mathematical Society, EarlyView.
Abstract We devise an explicit method for computing combinatorial formulae for Hadamard products of certain rational generating functions. The latter arise naturally when studying so‐called ask zeta functions of direct sums of modules of matrices or class‐ and orbit‐counting zeta functions of direct products of nilpotent groups.

φ−Hilfer Fractional Cauchy Problems with Almost Sectorial and Lie Bracket Operators in Banach Algebras

Fractal and Fractional
In the theory of Banach algebras, we use the Schauder fixed-point theorem to obtain some results that concern the existence property for mild solutions of fractional Cauchy problems that involve the Lie bracket operator, the almost sectorial operator ...

Minimal commutant and double commutant property for analytic Toeplitz operators

Banach Journal of Mathematical Analysis
Abstract In this paper, we study the minimality of the commutant of an analytic Toeplitz operator $$M_\varphi $$ M φ , when $$M_\varphi $$

Étale motives of geometric origin

Bulletin of the London Mathematical Society, EarlyView.
Abstract Over qcqs finite‐dimensional schemes, we prove that étale motives of geometric origin can be characterised by a constructibility property which is purely categorical, giving a full answer to the question ‘Do all constructible étale motives come from geometry?’ which dates back to Cisinski and Déglise's work.

Presentation of kernels of rational characters of right‐angled Artin groups

Bulletin of the London Mathematical Society, EarlyView.
Abstract In this note, we characterise when the kernel of a rational character of a right‐angled Artin group, also known as generalised Bestiva–Brady group, is finitely generated and finitely presented. In these cases, we exhibit a finite generating set and a presentation.
