Rigid gauges and F-zips, and the fundamental sheaf of gauges Gn [PDF]

, 2009
We establish an equivalence of categories between a category of gauges and Moonens and Wedhorns category of F-zips.

Cohomology and the subgroup structure of a finite soluble group [PDF]

The main topic of this thesis is the discovery and study of a cohomological property of the subgroups called F-normalizers in finite soluble groups; namely, the property that with certain coefficient modules the restriction map in cohomology from a ...

Some Results on the Cohomology of Line Bundles on the Three Dimensional Flag Variety

Mathematics, 2019
Let k be an algebraically closed field of prime characteristic and let G be a semisimple, simply connected, linear algebraic group. It is an open problem to find the cohomology of line bundles on the flag variety G / B , where B is a Borel ...

Boundedness of cohomology

Journal of Algebra, 2010
Let $d \in \N$ and let $\D^d$ denote the class of all pairs $(R,M)$ in which $R = \bigoplus_{n \in \N_0} R_n$ is a Noetherian homogeneous ring with Artinian base ring $R_0$ and such that $M$ is a finitely generated graded $R$-module of dimension $\leq d$. The cohomology table of a pair $(R,M) \in \D^d$ is defined as the family of non-negative integers $

On Cohomological Decomposability of Almost-Kähler Structures [PDF]

, 2012
We study the J-invariant and J-anti-invariant cohomological subgroups of the de Rham cohomology of a compact manifold M endowed with an almost-K\"ahler structure (J, \omega, g).

Vanishing results for the cohomology of complex toric hyperplane complements [PDF]

Suppose R is the complement of an essential arrangement of toric hyperlanes in the complex torus and ? = ?1(R). We show that H*(R;A) vanishes except in the top degree n when A is one of the following systems of local coefficients: (a) a system of ...

KV. Cohomology and some applications [PDF]

, 2020
Two versions of the KV-cohomology are presented and some algebraic and geometrical applications are given. We will see some applications to stochastic manifold. As a consequence, we can apply these ideas in Lorentzian geometry, in particular in

Cohomology and Crossed Modules of Modified Rota–Baxter Pre-Lie Algebras

Mathematics
The goal of the present paper is to provide a cohomology theory and crossed modules of modified Rota–Baxter pre-Lie algebras. We introduce the notion of a modified Rota–Baxter pre-Lie algebra and its bimodule.

A lattice U(1) Chern-Simons theory via lattice Deligne-Beilinson cohomology

Journal of High Energy Physics
We define Deligne-Beilinson (DB) cohomology on a cubic lattice and use it to formulate and analyze lattice U(1) Chern-Simons theory at even levels. The continuum DB cohomology provides a refined mathematical framework for continuum U(1) connections ...
