Abelian Livšic theorems for Anosov flows
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract We give two short proofs of the abelian Livšic theorem of Gogolev and Rodriguez Hertz. We show that these proofs may be extended to give new abelian Livšic theorems for positive density sets of null‐homologous orbits and for amenable covers.

Non-Abelian Majorana Doublets in Time-Reversal-Invariant Topological Superconductors
Physical Review X, 2014 The study of non-Abelian Majorana zero modes advances our understanding of the fundamental physics in quantum matter and pushes the potential applications of such exotic states to topological quantum computation. It has been shown that in two-dimensional

A generalization of Kruyswijk-Olson theorem on Davenport constant in commutative semigroups
AIMS Mathematics, 2020 Let $\mathcal{S}$ be a finite commutative semigroup written additively. An element $e$ of $\mathcal{S}$ is said to be idempotent if $e+e=e$. The Erdős-Burgess constant of the semigroup $\mathcal{S}$ is defined as the smallest positive integer $\ell$ such

Multipliers on weighted Hardy spaces over certain totally disconnected groups
International Journal of Mathematics and Mathematical Sciences, 1988 In this note, we consider the multipliers on weighted H1 spaces over totally disconnected locally compact abelian groups with a suitable sequence of open compact subgroups (Vilenkin groups).

Partition theorems for Abelian groups
Journal of Combinatorial Theory, Series A, 1975 AbstractLet A be a finite matrix with integral entries and G be an Abelian group. Define A to be partition regular in G if for every partition of G/(0) into finitely many classes there exist elemens x1,…,xm contained in one class such that A(x1,…,xm)T = 0. Theorem. A is partition regular in G iff at least one of the following statements holds.

Addition theorems in elementary Abelian groups, I
Journal of Number Theory, 1987 Let \(G\) be a commutative finite group. Given a sequence \(S=(a_1,\ldots,a_n)\) of elements of \(G\), \(a_i\neq 1\), define \[ \Sigma (S)=\{a_{i_1} a_{i_2}\cdots a_{i_k}: 1\leq ...

On elementarity of radical classes of modules over noncommutative dedekind duo-domains
Karpatsʹkì Matematičnì Publìkacìï, 2012 We find some sufficient conditions for a radical class of an idempotent radical in the category of modules over a Dedekind left bounded duo-domain to be axiomatisable. In the case of the integer numbers ring this result implies the Gorbachuk-Komarnitskii
