The null-cone and cohomology of vector bundles on flag manifolds

Kari Vilonen, Ting Xue

Published 2015-05-28Version 1

We study the null-cone of a semi-simple algebraic group acting on a number of copies of its Lie algebra via the diagonal adjoint action. We show that neither this variety, nor its normalization, has rational singularities in general.
