Spin-preserving Knuth correspondences for ribbon tableaux
Marc A. A. Van Leeuwen
The RSK correspondence generalises the Robinson-Schensted correspondence by replacing permutation matrices by matrices with entries in , and standard Young tableaux by sem…
Some bijective correspondences involving domino tableaux
Marc A. A. van Leeuwen
We define a number of new combinatorial operations on skew semistandard domino tableaux, which together with constructions introduced earlier by C. Carre and B. Leclerc, define an…
The Littlewood-Richardson rule, and related combinatorics
Marc A. A. van Leeuwen
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,…
Flag varieties and interpretations of Young tableau algorithms
Marc A. A. van Leeuwen
The conjugacy classes of nilpotent matrices can be parametrised by partitions of , and for a nilpotent in the class parametrised by , the variety of…
