The RSK correspondence generalises the Robinson-Schensted correspondence by replacing permutation matrices by matrices with entries in N, and standard Young tableaux by semistandard ones. For r âˆˆâ€¦ (More)

Littelmann has given a combinatorial model for the characters of representations of semisimple Lie algebras, in terms of certain paths traced in the space of (rational) weights. From it, aâ€¦ (More)

The conjugacy classes of nilpotent n Ã— n matrices can be parametrised by partitions Î» of n, and for a nilpotent Î· in the class parametrised by Î», the variety FÎ· of Î·-stable flags has its irreducibleâ€¦ (More)

An introduction is given to the Littlewood-Richardson rule, and various combinatorial constructions related to it. We present a proof based on tableau switching, dual equivalence, and coplacticâ€¦ (More)

We elaborate on the results in [CaLe]. We give bijective proofs of a number of identities that were established there, in particular between the Yamanouchi domino tableaux and theâ€¦ (More)

An overview is provided of some of the basic facts concerning rim hook lattices and ribbon tableaux, using a representation of partitions by their edge sequences. An action is defined of the affineâ€¦ (More)

We discuss several well known results about Schur functions that can be proved using cancellations in alternating summations; notably we shall discuss the Pieri and Murnaghan-Nakayama rules, theâ€¦ (More)

On January 8, 2007, just before 9 in the morning, a computer finished writing to disk about sixty gigabytes of files containing the Kazhdan-Lusztig polynomials for the split real group G of type E8.â€¦ (More)

We introduce a set of operations that we call crystal operations on matrices with entries either in {0, 1} or in N. There are horizontal and vertical forms of these operations, which commute withâ€¦ (More)
