Pairings, duality, amenability and bounded cohomology
We give a new perspective on the homological characterisations of amenability given by Johnson and Ringrose in the context of bounded cohomology and by Block and Weinberger in the context of uniformly finite homology.

Schwinger-Keldysh formalism. Part II: thermal equivariant cohomology
Causally ordered correlation functions of local operators in near-thermal quantum systems computed using the Schwinger-Keldysh formalism obey a set of Ward identities.

Fibers of rational maps and Rees algebras of their base ideals
We consider a ratinonal map $\phi$ from m-dimensional projective space to n-dimensional projective space that is a parameterization of m-dimensional variety. Our main goal is to study the (m-1)-dimensional fibers of $\phi$ in relation with the m-th local

Upper bounds and attached primes of top local cohomology modules defined by a pair of ideals [PDF]
Throughout R is a Noetherian local ring. In this paper we study cohomological dimension of an R-module M with respect to a pair of ideals and some of its relations with the attached prime ideals of M and the cohomological dimension of M with respect to ...

Localization sequences for logarithmic topological cyclic homology
Abstract We introduce the notion of an Ek$\mathbb {E}_k$‐ring with prelogarithmic structure, define logarithmic topological Hochschild homology and logarithmic topological cyclic homology in this context, and establish localization sequences for these theories. Our approach is based on Thom R$R$‐algebras.

Local Cohomology and ?ech Complexes [PDF]
[[abstract]]讓 (R,m) 是一個 Noetherian local ring 以及讓C是關於這一個sequence x1,x2,…,xn 的?ech complex。如果這個ideal ( x1,x2,…,xn) 是m-primary,那麼我們知道 local cohomology 跟?ech complex 會有某種的同構關係。在本篇論文裡,我們會針對這個已知的事實給一個完整的證明。

The L-two cohomology of Artin groups
For each Artin group we compute the reduced ℓ2-cohomology of its 'Salvetti complex'. This is a CW-complex which is conjectured to be a model for the classifying space of the Artin group. When this conjecture is known to hold our calculation describes the

Higher representation stability for ordered configuration spaces
Abstract Using factorization homology with coefficients in twisted commutative algebras (TCAs), we prove two flavors of higher representation stability for the cohomology of (generalized) configuration spaces of a scheme/topological space X$X$. First, we provide an iterative procedure to study higher representation stability using actions coming from ...

Poisson and Hochschild cohomology and the semiclassical limit [PDF]
Let $B$ be a quantum algebra possessing a semiclassical limit $A$. We show that under certain hypotheses $B^e$ can be thought of as a deformation of the Poisson enveloping algebra of $A$, and we give a criterion for the Hochschild cohomology of $B$ to

ABSTRACT LOCAL COHOMOLOGY FUNCTORS [PDF]
We propose to define the notion of abstract local cohomology functors. The ordinary local cohomology functor RΓI with support in the closed subset defined by an ideal I and the generalized local cohomology functor RΓI,J defined in [16] are characterized ...
