A Chevalley formula for semi-infinite flag manifolds and quantum K-theory (Extended abstract)
Cristian Lenart, Satoshi Naito, Daisuke Sagaki
We give a combinatorial Chevalley formula for an arbitrary weight, in the torus-equivariant K-theory of semi-infinite flag manifolds, which is expressed in terms of the quantum alc…

On Combinatorial Models for Affine Crystals
Cristian Lenart, Adam Schultze
We biject two combinatorial models for tensor products of (single-column) Kirillov-Reshetikhin crystals of any classical type : the quantum alcove model and the tableau model.…
