On combinatorics of string polytopes in types and
Yunhyung Cho, Naoki Fujita, Eunjeong Lee
A string polytope is a rational convex polytope whose lattice points parametrize a highest weight crystal basis, which is obtained from a string cone by explicit affine inequalitie…
Enumeration of Gelfand-Cetlin type reduced words
Yunhyung Cho, Jang Soo Kim, Eunjeong Lee
The combinatorics of reduced words and commutation classes plays an important role in geometric representation theory. A string polytope is a lattice polytope associated to each re…
On the combinatorics of string polytopes
Yunhyung Cho, Yoosik Kim, Eunjeong Lee +1
For a reduced word of the longest element in the Weyl group of , one can associate the string cone which parametrizes the dual…
On the f-vectors of Gelfand-Cetlin polytopes
Byung Hee An, Yunhyung Cho, Jang Soo Kim
A Gelfand-Cetlin polytope is a convex polytope obtained as an image of certain completely integrable system on a partial flag variety. In this paper, we give an equivalent descript…
