The nilpotence conjecture in K-theory of toric varieties
arXiv:math/0209112
Abstract
It is shown that all nontrivial elements in higher -groups of toric varieties over a class of regular rings are annihilated by iterations of the natural Frobenius type endomorphisms. This is a higher analog of the triviality of vector bundles on affine toric varieties.
