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 and and the flip Stiefel manifolds. We also pr…
Good objects in the equivariant world
Surojit Ghosh, Bikramjit Kundu
This article explores equivariant localization in the category of -spaces, where is a compact Lie group. We establish a commutation rule for the localization functor and the…
The index of certain Stiefel manifolds
Samik Basu, Bikramjit Kundu
This paper computes the Fadell-Husseini index of Stiefel manifolds in the case where the group acts via permutations of the orthogonal vectors. The computations are carried out in…
-triviality of low dimensional manifolds
Aritra C Bhattacharya, Bikramjit Kundu, Aniruddha C Naolekar
A space is -trivial if for every real vector bundle over the total Stiefel-Whitney class is 1. It follows from a result of Milnor that if is an orientab…
