Construction of Equivariant Vector Bundles

چکیده
Let X be the wonderful compactification of a complex adjoint symmetric space G/K such that rk(G/K) = rk(G) − rk(K). We show how to extend equivariant vector bundles on G/K to equivariant vector bundles on X , generated by their global sections and having trivial higher cohomology groups. This relies on a geometric construction of equivariant vector bundles in the setting of varieties with reductive group action and “multiplicity-free” subvarieties.

A Global View of Equivariant Vector Bundles and Dirac Operators on Some Compact Homogeneous Spaces
In order to facilitate the comparison of Riemannian homogeneous spaces of compact Lie groups with noncommutative geometries (“quantizations”) that approximate them, we develop here the basic facts concerning equivariant vector bundles and Dirac operators over them in a way that uses only global constructions and arguments. Our approach is quite algebraic, using primarily the modules of cross-se...
متن کاملClassification of Equivariant Complex Vector Bundles over a Circle
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 complex vector bundles over a circle by investigating the extensions of representations. As a corollary of our results, we calculate the reduced equivariant K-group of a circle for any compact Lie group.
متن کاملThe Sigma Orientation for Analytic Circle-equivariant Elliptic Cohomology
We construct a canonical Thom isomorphism for virtual T-oriented T-equivariant spin bundles with vanishing Borel-equivariant second Chern class, which is natural under pull-back of vector bundles and exponential under Whitney sum. It extends in the rational case the non-equivariant sigma orientation of Hopkins, Strickland, and the author. The construction relates the sigma orientation to the re...
متن کامل2 Equivariant vector bundles on group completions
We describe the category of equivariant vector bundles on a smooth (partial) group completion of an adjoint simple algebraic group. As a corollary of our description, we prove that every equivariant vector bundle of rank less than or equal to rkG on the canonical (wonderful) completion splits into a direct sum of line bundles.
