Persistent equivariant cohomology

This article has two goals. First, we hope to give an accessible introduction to persistent equivariant cohomology. Given a topological group $G$ acting on a filtered space, persistent Borel equivariant cohomology measures not only the shape of the filtration, but also attributes of the group action on the filtration, including in particular its fixed ...

The equivariant B model

Journal of High Energy Physics
In this work, we introduce an equivariant deformation of the B model on the sphere with a U(1)-action. We present the deformed supersymmetry transformations and corresponding Lagrangians and study observables in the supercharge cohomology.

Effective action for relativistic hydrodynamics: fluctuations, dissipation, and entropy inflow

Journal of High Energy Physics, 2018
We present a detailed and self-contained analysis of the universal SchwingerKeldysh effective field theory which describes macroscopic thermal fluctuations of a relativistic field theory, elaborating on our earlier construction [1]. We write an effective

G-Spaces with Prescribed Equivariant Cohomology [PDF]

Proceedings of the American Mathematical Society, 1983
Let G G be a finite group. In this note we study the question of realizing a collection of graded commutative algebras over Q {\mathbf {Q}} as the cohomology algebras with rational coefficients of the fixed point sets X H (

On the weight zero compactly supported cohomology of ${\mathcal {H}}_{g,n}$

Forum of Mathematics, Sigma
For $g\ge 2$ and $n\ge 0$ , let $\mathcal {H}_{g,n}\subset \mathcal {M}_{g,n}$ denote the complex moduli stack of n-marked smooth hyperelliptic curves of genus g.

Equivariant Cohomology for Cyclic Groups

International Mathematics Research Notices
Abstract In this paper, we compute the $RO(C_{n})$-graded coefficient ring of equivariant cohomology for cyclic groups $C_{n}$, in the case of Burnside ring coefficients, and in the case of constant coefficients. We use the invertible Mackey functors under the box product to reduce the gradings in the computation from $RO(C_{n})$ to ...
