$K$ -theory of Flag Bott manifolds

Bidhan Paul, Vikraman Uma

The aim of this paper is to describe the topological $K$ -ring, in terms of generators and relations of a flag Bott manifold. We apply our results to give a presentation for the top…

GKM graph locally modeled by $T^{n} \times S^{1}$ -action on $T^{*} C^{n}$ and its graph equivariant cohomology

Shintaro Kuroki, Vikraman Uma

We introduce a class of labeled graphs (with legs) which contains two classes of GKM graphs of $4 n$ -dimensional manifolds with $T^{n} \times S^{1}$ -actions, i.e., GKM graphs of the…

$K$ -theory of $\mbox{hyperKähler}$ toric manifolds

V. Uma

Let $X$ be a toric $\mbox{hyperKähler}$ manifold. The purpose of this note is to describe the topological $K$ -ring $K^{*} (X)$ of $X$ . We give a presentation for the topological $K$ -r…
