Equivariant K-groups of spheres with actions of involutions
Jin-Hwan Cho, Mikiya Masuda
We calculate the R(G)-algebra structure on the reduced equivariant K-groups of two-dimensional spheres on which a compact Lie group G acts as involutions. In particular, the reduce…
Classification of equivariant real vector bundles over a circle
Jin-Hwan Cho, Sung Sook Kim, Mikiya Masuda +1
This is a continuation of the authors' previous work [math.AT/9910001] on classification of equivariant complex vector bundles over a circle. In this paper we classify equivariant…
On extensions of representations for compact Lie groups
Jin-Hwan Cho, Min Kyu Kim, Dong Youp Suh
Let be a closed normal subgroup of a compact Lie group such that is connected. This paper provides a necessary and sufficient condition for every complex representati…
Classification of Equivariant Complex Vector Bundles over a Circle
Jin-Hwan Cho, Sung Sook Kim, Mikiya Masuda +1
In this paper we characterize the fiber representations of equivariant complex vector bundles over a circle and classify these bundles. We also treat the triviality of equivariant…
