Affine open covering of the quantized flag manifolds at roots of unity

[摘要] We show that the quantized flag manifold at a root of unity has natural affine open covering parametrized by the elements of the Weyl group. In particular, the quantized flag manifold turns out to be a quasi-scheme in the sense of Rosenberg [12]. (C) 2021 Elsevier Inc. All rights reserved.
