Finiteness Theorems for Deformations of Complexes [PDF]
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 ...

Homological finiteness conditions for groups, monoids and algebras
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
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

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]
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]
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
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
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]
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 $1<p\le2$.
