Identities of inverse Chevalley type for graded characters of level-zero Demazure submodules over quantum affine algebras of type C
Takafumi Kouno, Satoshi Naito, Daniel Orr
We provide identities of inverse Chevalley type for the graded characters of level-zero Demazure submodules of extremal weight modules over a quantum affine algebra of type . Th…

Closed -Schur Katalan functions as -homology Schubert representatives of the affine Grassmannian
Takeshi Ikeda, Shinsuke Iwao, Satoshi Naito
Recently, Blasiak-Morse-Seelinger introduced symmetric functions called Katalan functions, and proved that the -theoretic -Schur functions due to Lam-Schilling-Shimozono form…
