Equivariant cohomological rigidity for four-dimensional Hamiltonian $\mathbf{S^1}$-manifolds [PDF]

open access: yesarXiv
For manifolds equipped with group actions, we have the following natural question: To what extent does the equivariant cohomology determine the equivariant diffeotype? We resolve this question for Hamiltonian circle actions on compact, connected symplectic four-manifolds.

Equivariant Simplicial Cohomology With Local Coefficients and its Classification [PDF]

open access: yesarXiv, 2009
We introduce equivariant twisted cohomology of a simplicial set equipped with simplicial action of a discrete group and prove that for suitable twisting function induced from a given equivariant local coefficients, the simplicial version of Bredon-Illman cohomology with local coefficients is isomorphic to equivariant twisted cohomology.
