Non-trivial extensions in equivariant cohomology with constant coefficients

Samik Basu, Surojit Ghosh

In this paper, we prove some computational results about equivariant cohomology over the cyclic group $C_{p^{n}}$ of prime power order. We show that there is an inductive formula whe…

Mapping algebras and the Adams spectral sequence

David Blanc, Surojit Ghosh

The $E_{2}$ -term of the Adams spectral sequence for $Y$ may be described in terms of its cohomology $E^{*} Y$ , together with the action of the primary operations $…

Bredon cohomology of finite dimensional $C_{p}$ -spaces

Samik Basu, Surojit Ghosh

For finite dimensional free $C_{p}$ -spaces, the calculation of the Bredon cohomology ring as an algebra over the cohomology of $S^{0}$ is used to prove the non-existence of certain $C_…
