Module structure of Weyl algebras

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract The seminal paper (Stafford, J. Lond. Math. Soc. (2) 18 (1978), no. 3, 429–442) was a major step forward in our understanding of Weyl algebras. Beginning with Serre's Theorem on free summands of projective modules and Bass' Stable Range Theorem in commutative algebra, we attempt to trace the origins of this work and explain how it led to ...

Siegel–Veech constants for cyclic covers of generic translation surfaces

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We compute the asymptotic number of cylinders, weighted by their area to any nonnegative power, on any cyclic branched cover of any generic translation surface in any stratum. Our formulae depend only on topological invariants of the cover and number‐theoretic properties of the degree: in particular, the ratio of the related Siegel–Veech ...

Modeling Spiral Chaos in Predator–Prey Dynamics Using Implicit Integration Factor Schemes

open access: yesComputational and Mathematical Methods, Volume 2026, Issue 1, 2026.
This paper presents efficient implicit integration factor (IIF) methods as robust alternatives to classical finite difference schemes for the numerical solution of nonlinear time‐dependent reaction–diffusion equations in one and two spatial dimensions.

Distributivity versus associativity in the homology theory of algebraic structures

open access: yes, 2011
While homology theory of associative structures, such as groups and rings, has been extensively studied in the past beginning with the work of Hopf, Eilenberg, and Hochschild, homology of non-associative distributive structures, such as quandles, were ...

Construct bi-frobenius algebras via the Benson-Carlson quotient rings

open access: yes, 2018
Let H be a finite dimensional spherical Hopf algebra, r(H) the Green ring of H and P the ideal of r(H) generated by all H-modules of quantum dimension zero. Using dimensions of negligible morphism spaces, we define a bilinear form on the Green ring r(H).

Graduaciones elementales sobre el álgebra de Lie de matrices triangulares superiores [PDF]

open access: yes, 2023
Este trabajo se enfoca en el álgebra de Lie UTn(K)(−), es decir, las matrices triangulares superiores de orden n con el producto de Lie. Se describe la graduación elemental sobre el álgebra de Lie UTn(K)(−) y se presenta la graduación canónica por el ...

Cálculo differencial no conmmutativo de algunas álgebras de tipo polinomial con bases PBW

open access: yes, 2020
In this work, we study the notion of differential calculus associated to an associative algebra, from its origin in manifolds geometry, to some generalizations in non commutative differential geometry.

$L$-infinity and $A$-infinity structures [PDF]

open access: yes, 2019
summary:Looking back over 55 years of higher homotopy structures, I reminisce as I recall the early days and ponder how they developed and how I now see them. From the history of $A_\infty$-structures and later of $L_\infty$-structures and their progeny,
