The theorem of Bochner for adjointable operators valued maps

open access: yesEuropean Journal of Mathematics and Applications, 2023
In this paper, we obtain a generalisation of Bochner’s theorem to positive definite functions defined on a locally compact abelian group with values in the space of adjointable operators on a Hilbert C*-module.

Polynomial Growth Harmonic Functions on Finitely Generated Abelian Groups

open access: yes, 2013
In the present paper, we develop geometric analytic techniques on Cayley graphs of finitely generated abelian groups to study the polynomial growth harmonic functions.

Aggregation and the Structure of Value

open access: yesNoûs, EarlyView.
ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

Abelian theorem for the Stieltjes transform of distributions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
First, a definition is given of the Stieltjes transform of distributions which contains some well-known. Then, a structural theorem for distributions having S-asymptotic is proved.

Equivariant toric geometry and Euler–Maclaurin formulae

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.
Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Infinite locally finite groups groups with the given properties of the norm of Abelian non-cyclic subgroups

open access: yesМатематичні Студії
In the paper, the properties of infinite locally finite groups with non-Dedekind locally nil\-potent norms of Abelian non-cyclic subgroups are studied. It is proved that such groups are finite extensions of a quasicyclic subgroup and contain Abelian non ...

Infinite-dimensional fermionic symmetry in supersymmetric gauge theories

open access: yesJournal of High Energy Physics, 2021
We establish the existence of an infinite-dimensional fermionic symmetry in four-dimensional supersymmetric gauge theories by analyzing semiclassical photino dynamics in abelian N $$ \mathcal{N} $$ = 1 theories with charged matter.

Covering groups and their applications: A survey

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2022
This article is a survey of covering group theorems and their applications. For a given covering mapping from the topological space onto a topological group, it is natural to pose the following question on the lifting of the group structure from the base

Approximate groups and doubling metrics

open access: yes, 2012
We develop a version of Freiman's theorem for a class of non-abelian groups, which includes finite nilpotent, supersolvable and solvable A-groups. To do this we have to replace the small doubling hypothesis with a stronger relative polynomial growth ...

Local equivalence and refinements of Rasmussen's s‐invariant

open access: yesJournal of Topology, Volume 19, Issue 1, March 2026.
Abstract Inspired by the notions of local equivalence in monopole and Heegaard Floer homology, we introduce a version of local equivalence that combines odd Khovanov homology with equivariant even Khovanov homology into an algebraic package called a local even–odd (LEO) triple.
