Molecules of an affine FPF $W$ -graph and a labelled row-Beissinger reconstruction

Yifeng Zhang

Kazhdan--Lusztig $W$ -graphs encode the cell structure of Hecke algebras, while their bidirected connected components are called molecules. In finite type~ $A$ , the Robinson--Schenst…

Dual Weight and Monodromy of Dual Affine RS Correspondence

Yifeng Zhang

The dual affine Robinson--Schensted correspondence and the affine matrix-ball construction give two related parametrizations of extended affine permutations. From the stable-window…

Recursive structures of molecules and cells in Gelfand $S_{n}$ -graphs

Zhiqiang Dai, Yifeng Zhang

$W$ -graphs, representing the multiplication action of the standard basis on the canonical basis in the Iwahori-Hecke algebra are introduced by Kazhdan and Lusztig. Marberg defined…
