COMBINATORICS OF CANONICAL BASES REVISITED: STRING DATA IN TYPE A
Abstract We give a formula for the crystal structure on the integer points of the string polytopes and the *-crystal structure on the integer points of the string cones of type A for arbitrary reduced words. As a byproduct, we obtain defining inequalities for Nakashima–Zelevinsky string polytopes. Furthermore, we give …
