Finiteness Theorems for Deformations of Complexes [PDF]

open access: yes, 2010
We consider deformations of bounded complexes of modules for a profinite group G over a field of positive characteristic. We prove a finiteness theorem which provides some sufficient conditions for the versal deformation of such a complex to be ...

Two-electrode design for electrostatic ion trap integrable in polar coordinates

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019
Field with additive quadratic dependence on one of coordinates guarantees charged particle motion equation integrability was studied. Ion motion finiteness conditions in electrostatic ion trap are found.

Homological finiteness conditions for groups, monoids and algebras

open access: yes, 2006
Recently Alonso and Hermiller introduced a homological finiteness condition\break $bi{-}FP_n$ (here called {\it weak} $bi{-}FP_n$) for monoid rings, and Kobayashi and Otto introduced a different property, also called $bi{-}FP_n$ (we adhere to their ...

Asymptotic Charges at Null Infinity in Any Dimension

open access: yesUniverse, 2018
We analyse the conservation laws associated with large gauge transformations of massless fields in Minkowski space. Our aim is to highlight the interplay between boundary conditions and finiteness of the asymptotically conserved charges in any space-time

Urbino, ou l’histoire des relations de coévolution entre un établissement humain et son milieu naturel

open access: yesLes Cahiers de la Recherche Architecturale, Urbaine et Paysagère, 2021
In the field of architecture, the finiteness of resources is a generally accepted observation and, in recent years, has given rise to a multitude of debates and practices, albeit not without ambiguities.

Asymptotically anti-de Sitter space-times: symmetries and conservation laws revisited [PDF]

open access: yes, 2003
In this short note, we verify explicitly in static coordinates that the non trivial asymptotic Killing vectors at spatial infinity for anti-de Sitter space-times correspond one to one to the conformal Killing vectors of the conformally flat metric ...

IDEALS AND FINITENESS CONDITIONS FOR SUBSEMIGROUPS [PDF]

open access: yesGlasgow Mathematical Journal, 2013
AbstractIn this paper we consider a number of finiteness conditions for semigroups related to their ideal structure, and ask whether such conditions are preserved by sub- or supersemigroups with finite Rees or Green index. Specific properties under consideration include stability,$\mathcal{D}=\mathcal{J}$and minimal conditions on ideals.

Green function method for a fractional–order delay differential equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
In this paper, we investigated a boundary value problem with the Sturm-Liouville type conditions for a linear ordinary differential equation of fractional order with delay. The condition for the unique solvability of the problem is obtained in the form △

Cohomological Finiteness Conditions in Bredon Cohomology

open access: yes, 2009
We show that any soluble group $G$ of type Bredon-$\FP_{\infty}$ with respect to the family of all virtually cyclic subgroups such that centralizers of infinite order elements are of type $\FP_{\infty}$ must be virtually cyclic.

Generalized absolute convergence of single and double Vilenkin-Fourier series and related results [PDF]

open access: yesMathematica Bohemica
We consider the Vilenkin orthonormal system on a Vilenkin group $G$ and the Vilenkin-Fourier coefficients $\hat{f}(n)$, $n\in\mathbb{N}$, of functions $f\in L^p(G)$ for some $1<p\le2$.
