(Co)homology of triassociative algebras

International Journal of Mathematics and Mathematical Sciences, 2006
We study homology and cohomology of triassociative algebras with nontrivial coefficients. The cohomology theory is applied to study algebraic deformations of triassociative algebras.

Amenability Constants for Unconditional Sums of Banach Algebras

Mathematische Nachrichten, Volume 299, Issue 9, Page 2472-2494, September 2026.
ABSTRACT We study Johnson amenability for unconditional direct sums of Banach algebras. Given a family (Ai)i∈I$(A_i)_{i\in I}$ of Banach algebras and a Banach sequence lattice E$E$ on I$I$, the E$E$‐sum ⨁i∈IAiE${\bigl (\bigoplus _{i\in I} A_i\bigr)}_{\!E}$ carries a natural Banach algebra structure via coordinatewise multiplication.

On Cohomological Triviality [PDF]

Proceedings of the American Mathematical Society, 1967
PROOF. As usual we proceed by induction on the order n= I GI. The theorem is trivial for n= 1. Suppose n> 1 and assume the truth of the theorem for all groups of order

Cohomology of Reynolds Lie Triple Systems and Applications

Axioms
We establish a cohomology theory for Reynolds Lie triple systems by first developing their representation theory and then assembling the corresponding cochains into a suitable complex.

A note on Gersten’s conjecture for étale cohomology over two-dimensional henselian regular local rings

Comptes Rendus. Mathématique, 2020
We prove Gersten’s conjecture for étale cohomology over two dimensional henselian regular local rings without assuming equi-characteristic. As an application, we obtain the local-global principle for Galois cohomology over mixed characteristic two ...

Singularity of non‐pluripolar cohomology classes

Bulletin of the London Mathematical Society, Volume 58, Issue 9, September 2026.
Abstract We establish a relation between Lelong numbers and the full mass property of relative non‐pluripolar products. We use this relation to prove that if the restricted volume of a big class α$\alpha$ along an effective divisor D$D$ has full mass, then the Lelong numbers of the non‐pluripolar class ⟨αn−1⟩$\langle \alpha ^{n-1}\rangle$ at every ...

On Finiteness Properties of Local Cohomology Modules [PDF]

, 2022
openThis thesis has its foundations in the fields of homological and commutative algebra, in particular in the study of local cohomology. Local cohomology was introduced by Grothendieck in the early 1960s, in part to answer a conjecture of Pierre Samuel ...

The triviality of dihedral cohomology for operator algebras

Scientific African
This article delves into algebraic topology, specifically (co)homology theory, which is essential in various mathematical fields. It explores different types of (co)homology groups such as Hochschild, cyclic, reflexive, and dihedral, focusing on dihedral
