Reconstructing a bijection on the level of Le diagrams

Abstract

Lukowiski, Parisi, and Williams formulated the T-duality map of string theory at a purely combinatorial level as a map on decorated permutations. We combinatorially describe this map at the level of Le diagrams. This perspective makes the dimension shift under the map more transparent.
