Littlewood-Richardson fillings and their symmetries
Abstract Considering the classical definition of the Littlewood-Richardson rule and its 2-dimensional representation by means of rectangular tableaux, we exhibit 24 symmetries of this rule when considering dualization, conjugation and their composition. Extending the Littlewood-Richardson rule to sequences of nonnegative real numbers, six of these symmetries may be generalized. Our point is to ...
متن کاملFrom Littlewood-richardson Sequences to Subgroup Embeddings and Back
Abstract. Let α, β, and γ be partitions describing the isomorphism types of the finite abelian p-groups A, B, and C. From theorems by Green and Klein it is well-known that there is a short exact sequence 0→ A→ B → C → 0 of abelian groups if and only if there is a Littlewood-Richardson sequence of type (α, β, γ). Starting from the observation that a sequence of partitions has the LR property if ...
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...
متن کاملLittlewood-richardson Semigroups
This note is an extended abstract of my talk at the workshop on Representation Theory and Symmetric Functions, MSRI, April 14, 1997. We discuss the problem of finding an explicit description of the semigroup LRr of triples of partitions of length ≤ r such that the corresponding Littlewood-Richardson coefficient is non-zero. After discussing the history of the problem and previously known result...
