Hankel transforms in generalized Fock spaces

International Journal of Mathematics and Mathematical Sciences, 1994
A classical Fock space consists of functions of the form,ϕ↔(ϕ0,ϕ1,…,ϕq),where ϕ0∈ℂ and ϕq∈Lp(ℝq), q≥1. We will replace the ϕq, q≥1 with test functions having Hankel transforms.

A note on the quasi‐local algebra of expander graphs

Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract We show that the quasi‐local algebra of a coarse disjoint union of expander graphs does not contain a Cartan subalgebra isomorphic to ℓ∞$\ell _\infty$. Ozawa has recently shown that these algebras are distinct from the uniform Roe algebras of expander graphs, and our result describes a further difference.

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.

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 ...

Topology of 3-dimensional manifolds [PDF]

ریاضی و جامعه
This is the second paper from a trio which reviews some of the progress in low dimensional topology in the past century. Starting with the work of Poincare in the last years of 19th century and first few years of 20th century, we review the major steps ...

Carrollian partition function for bulk Yang-Mills theory

Journal of High Energy Physics
The path integral over massless quantum fields in Minkowski space with scattering boundary conditions defines a Carrollian partition function on the null boundary.

Abelian and Tauberian results for the fractional Fourier cosine (sine) transform

AIMS Mathematics
In this paper, we presented Tauberian type results that intricately link the quasi-asymptotic behavior of both even and odd distributions to the corresponding asymptotic properties of their fractional Fourier cosine and sine transforms.
