Eigencone, saturation and Horn problems for symplectic and odd orthogonal groups
Prakash Belkale, Shrawan Kumar
We consider the eigenvalue problem and the associated intersection theory of homogenous spaces for the symplectic and odd orthogonal groups. We solve the Horn and saturation proble…
Special isogenies and tensor product multiplicities
Shrawan Kumar, John R. Stembridge
We show that any bijection between two root systems that preserves angles (but not necessarily lengths) gives rise to inequalities relating tensor product multiplicities for the co…
Descent of line bundles to GIT quotients of flag varieties by maximal torus
Shrawan Kumar
Let L be a homogeneous ample line bundle on any flag variety G/P and let T be a maximal torus of G. We prove a general necessary and sufficient condition for L to descend as a line…
Characters of simplylaced nonconnected groups versus characters of nonsimplylaced connected groups
Shrawan Kumar, George Lusztig, Dipendra Prasad
In this paper we show how a theorem of Jantzen relating the character of a finite dimensional irreducible representation of a disconnected semisimple algebraic group on elements ou…
