Equivariant differential cohomology

Transactions of the American Mathematical Society, 2018
The construction of characteristic classes via the curvature form of a connection is one motivation for the refinement of integral cohomology by de Rham cocycles -- known as differential cohomology. We will discuss the analog in the case of a group action on the manifold: The definition of equivariant characteristic forms in the Cartan model due to ...

Quadratic differentials and equivariant deformation theory of curves [PDF]

, 2012
Given a finite p-group G acting on a smooth projective curve X over an algebraically closed field k of characteristic p, the dimension of the tangent space of the associated equivariant deformation functor is equal to the dimension of the space of ...

Topologically twisted SUSY gauge theory, gauge-Bethe correspondence and quantum cohomology

Journal of High Energy Physics, 2019
We calculate the partition function and correlation functions in A-twisted 2d N $$ \mathcal{N} $$ = (2, 2) U(N) gauge theories and topologically twisted 3d N $$ \mathcal{N} $$ = 2 U(N) gauge theories containing an adjoint chiral multiplet with particular

Generalized Equivariant Cohomology and Stratifications [PDF]

Canadian Mathematical Bulletin, 2016
AbstractFor T a compact torus and a generalized T-equivariant cohomology theory, we provide a systematic framework for computing in the context of equivariantly stratified smooth complex projective varieties. This allows us to explicitly compute as an (pt)-module when X is a direct limit of smooth complex projective Tℂ-varieties.

Bredon homology and equivariant K-homology of SL(3,Z) [PDF]

, 2008
We obtain the equivariant K-homology of the classifying space underline{E}SL(3,Z) from the computation of its Bredon homology with respect to finite subgroups and coefficients in the representation ring.

Overconvergent modular forms are highest-weight vectors in the Hodge-Tate weight zero part of completed cohomology

Forum of Mathematics, Sigma, 2021
We construct a $(\mathfrak {gl}_2, B(\mathbb {Q}_p))$ and Hecke-equivariant cup product pairing between overconvergent modular forms and the local cohomology at $0$ of a sheaf on $\mathbb {P}^1$, landing in the compactly supported completed $\mathbb {C ...

Stable rational cohomology of automorphism groups of free groups and the integral cohomology of moduli spaces of graphs [PDF]

, 2002
It is not known whether or not the stable rational cohomology groups H*(Aut(F[infinity]);Q) always vanish (see Hatcher in [5] and Hatcher and Vogtmann in [7] where they pose the question and show that it does vanish in the first 6 dimensions).

Equivariant Lie–Rinehart cohomology; pp. 294–300 [PDF]

Proceedings of the Estonian Academy of Sciences, 2010
In this paper we study Lie–Rinehart cohomology for quotients of singularities by finite groups, and interpret these cohomology groups in terms of integrable connection on modules.

Differentiable Stacks and Equivariant Cohomology

, 2019
In this thesis, we are interested in the study of cohomology of differentiable stacks and we want to provide a good notion of equivariant cohomology for differentiable stacks.

Sistemas de Cartan-Eilenberg en K-teoría Equivariante Torcida

Selecciones Matemáticas, 2020
The goal of this paper is to show explicitly the construction of a Cartan-Eilenberg system for the twisted equivariant K-theory groups of a finite G-CW complex, with G a finite group.
