Twisted bundles and twisted K-theory
Many papers have been devoted recently to twisted K-theory as originally defined in [15] and [29]. See for instance the references [2], [23] and the very accessible paper [30]. We offer here a more direct approach based on the notion of “twisted vector bundles”. This is not an entirely new idea, since we find it in [4], [6], [7], [8] and [9] for instance, under different names and from various ...
متن کاملOn the Torsion of Chow Groups of Twisted Spin-flags
In the present paper we provide a uniform bound for the annihilators of the torsion of the Chow groups of the variety of Borel subgroups of a strongly inner linear algebraic group of orthogonal type.
متن کاملTwisted Vector Bundles on Pointed Nodal Curves
This paper grew out of an attempt to understand a recent draft of Seshadri ([Se2]) and is meant as a contribution in the quest for a good compactification of the moduli space (or stack) of G-bundles on a nodal curve. We are led by the idea that such a compactification should behave well in families and also under partial normalization of nodal curves. This statement may be reformulated by sayin...
متن کاملChow Ring of Generically Twisted Varieties of Complete Flags
Let G be a split simple affine algebraic group of type A or C over a field k, and let E be a standard generic G-torsor over a field extension of k. We compute the Chow ring of the variety of Borel subgroups of G (also called the variety of complete flags of G), twisted by E. In most cases, the answer contains a large finite torsion subgroup. The torsion-free cases have been treated in the prede...
متن کاملTriviality of Vector Bundles on Sufficiently Twisted Ind-grassmannians
Twisted ind-Grassmannians are ind-varieties G obtained as direct limits of Grassmannians G(rm, V m), for m ∈ Z>0, under embeddings φm : G(rm, V m) → G(rm+1, V m+1) of degree greater than one. It has been conjectured in [PT] and [DP] that any vector bundle of finite rank on a twisted ind-Grassmannian is trivial. We prove this conjecture under the assumption that the ind-Grassmannian G is suffici...
