Multiplicity-free Products and Restrictions of Weyl Characters
نویسنده
چکیده
We classify all multiplicity-free products of Weyl characters, or equivalently, all multiplicity-free tensor products of irreducible representations of complex semisimple Lie algebras. As a corollary, we also obtain the classification of all multiplicity-free restrictions of irreducible representations to reductive subalgebras of parabolic type.

Restricting Unipotent Characters in Finite Symplectic Groups
We compute the irreducible constituents of the restrictions of all unipotent characters of the groups Sp4(q) and Sp6(q) and odd q to their maximal parabolic subgroups stabilizing a line. It turns out that these restrictions are multiplicity free. We also obtain general information about the restrictions of Harish-Chandra induced characters.
متن کاملMultiplicity-Free Products of Schur Functions
We classify all multiplicity-free products of Schur functions and all multiplicity-free products of characters of SL(n; C). 0. Introduction In this paper, we classify the products of Schur functions that are multiplicity-free; i.e., products for which every coeecient in the resulting Schur function expansion is 0 or 1. We also solve the slightly more general classiication problem for Schur func...
متن کاملAffinization of Category O for Quantum Groups
Let g be a simple Lie algebra. We consider the category Ô of those modules over the affine quantum group Uq(ĝ) whose Uq(g)-weights have finite multiplicity and lie in a finite union of cones generated by negative roots. We show that many properties of the category of the finite-dimensional representations naturally extend to the category Ô. In particular, we develop the theory of q-characters a...
متن کاملA Note on Certain Kronecker Coefficients
We prove an explicit formula for the tensor product with itself of an irreducible complex representation of the symmetric group defined by a rectangle of height two. We also describe part of the decomposition for the tensor product of representations defined by rectangles of heights two and four. Our results are deduced, through Schur-Weyl duality, from the observation that certain actions on t...
متن کاملMultiplicity-free theorems of the Restrictions of Unitary Highest Weight Modules with respect to Reductive Symmetric Pairs
The complex analytic methods have found a wide range of applications in the study of multiplicity-free representations. This article discusses, in particular, its applications to the question of restricting highest weight modules with respect to reductive symmetric pairs. We present a number of multiplicity-free branching theorems that include the multiplicity-free property of some of known res...
