Equivariant <i>K</i> -theory of cellular toric bundles and related spaces

Abstract In this article we describe the equivariant and ordinary topological K -ring of a toric bundle with fiber a T - cellular toric variety. This generalizes the results in [P. Sankaran and V. Uma, Cohomology of toric bundles, Comment. Math. Helv. 78 2003, 3, 540–554] on K -theory of smooth projective toric bundles. We apply our results to describe the equivariant topological K -ring of a toroidal horospherical embedding.
