Good objects in the equivariant world

Surojit Ghosh, Bikramjit Kundu

This article explores equivariant localization in the category of $G$ -spaces, where $G$ is a compact Lie group. We establish a commutation rule for the localization functor and the…

Some Observations on projective Stiefel Manifolds

Bikramjit Kundu, Sudeep Podder

In this note, we compute the upper characteristic rank of the projective Stiefel manifolds over $R, C$ and $H$ and the flip Stiefel manifolds. We also pr…

$W$ -triviality of low dimensional manifolds

Aritra C Bhattacharya, Bikramjit Kundu, Aniruddha C Naolekar

A space $X$ is $W$ -trivial if for every real vector bundle $α$ over $X$ the total Stiefel-Whitney class $w (α)$ is 1. It follows from a result of Milnor that if $X$ is an orientable…

The index of equidimensional flag manifolds

Samik Basu, Bikramjit Kundu

In this paper, we consider the flag manifold of $p$ orthogonal subspaces of equal dimension which carries an action of the cyclic group of order $p$ . We provide a complete calculat…

Some observations on the index of $C_{p}$ -spaces

Bikramjit Kundu

In this paper, we consider numerical indices associated to spaces with free $C_{p}$ -action. We prove that the Stiefel manifolds provide an example of non-tidy spaces for $p = 2$ , which…
