An Algorithm to compute the Kronecker cone and other moment cones
Michaël Bulois, Roland Denis, Nicolas Ressayre
We describe a new algorithm that computes the minimal list of inequalities for the moment cone of any representation of a complex reductive group, with implementation details for t…
HKKN-stratifications in a non-compact framework
Paul-Emile Paradan, Nicolas Ressayre
The aim of this paper is twofold. First, we study HKKN stratifications, both algebraically and analytically, for a Cartesian product between a vector space and a compact K{ä}hler m…
Intersection multiplicity one for the Belkale-Kumar product in G/B
Nicolas Ressayre, Luca Francone
Consider the complete flag variety of a complex semisimple algebraic group . We show that the structure coefficients of the Belkale-Kumar product , on the cohomolog…
Bidilatation of Small Littlewood-Richardson Coefficients
Pierre-Emmanuel Chaput, Nicolas Ressayre
The Littlewood-Richardson coefficients are the multiplicities in the tensor product decomposition of two irreducible representations of the general linear group GL$(n,…
Newell-Littlewood numbers III: eigencones and GIT-semigroups
Shiliang Gao, Gidon Orelowitz, Nicolas Ressayre +1
The Newell-Littlewood numbers are tensor product multiplicities of Weyl modules for the classical groups in the stable range. Littlewood-Richardson coefficients form a special case…
On the multiplicity spaces for branching to a spherical subgroup of minimal rank
Luca Francone, Nicolas Ressayre
Let g be a complex semi-simple Lie algebra and g be a semisimple subalgebra of g. Consider the branching problem of decomposing the simple g-representations V as a sum of simple gr…
