چکیده
We give an inductive procedure for finding the extremal rays of equivariant Littlewood-Richardson cone, which is closely related to solution space S. Friedland's majorized Hermitian eigenvalue problem. In so doing, we solve "rational version" a problem posed by C. Robichaux, H. Yadav, and A. Yong. Our natural extension P. Belkale's algorithm classical cone. The main tools accommodating setting are certain foundational results D. Anderson, E. Richmond, also study two families special cone make observations about Hilbert basis associated lattice semigroup.

Equivariant Littlewood-richardson Skew Tableaux
We give a positive equivariant Littlewood-Richardson rule also discovered independently by Molev. Our proof generalizes a proof by Stembridge of the ordinary Littlewood-Richardson rule. We describe a weight-preserving bijection between our indexing tableaux and the Knutson-Tao puzzles.
متن کاملGeometric realization of PRV components and the Littlewood–Richardson cone
Let X = G/B and let L1 and L2 be two line bundles on X. Consider the cup product map H1 (X,L1)⊗H q2 (X,L2) → H (X,L), where L = L1⊗L2 and q = q1+q2. We find necessary and sufficient conditions for this map to be a nonzero map of G–modules. We also discuss the converse question, i.e. given irreducible G–modules U and V , which irreducible components W of U⊗V may appear in the right hand side of ...
متن کاملCrystal Duality and Littlewood-richardson Rule of Extremal Weight Crystals
We consider a category of gl∞-crystals, whose object is a disjoint union of extremal weight crystals with bounded non-negative level and finite multiplicity for each connected component. We show that it is a monoidal category under tensor product of crystals and the associated Grothendieck ring is antiisomorphic to an Ore extension of the character ring of integrable lowest gl∞modules with resp...
متن کاملLittlewood–Richardson polynomials
We introduce a family of rings of symmetric functions depending on an infinite sequence of parameters. A distinguished basis of such a ring is comprised by analogues of the Schur functions. The corresponding structure coefficients are polynomials in the parameters which we call the Littlewood–Richardson polynomials. We give a combinatorial rule for their calculation by modifying an earlier resu...
متن کاملSmall Littlewood-Richardson coefficients
We develop structural insights into the Littlewood-Richardson graph, whose number of vertices equals the Littlewood-Richardson coefficient cνλ,μ for given partitions λ, μ and ν. This graph was first introduced in [BI12], where its connectedness was proved. Our insights are useful for the design of algorithms for computing the Littlewood-Richardson coefficient: We design an algorithm for the exa...
