The virtual cactus group and Littelmann paths

Representation Theory 2023-02-23 v1 Combinatorics

Abstract

We define a virtual cactus group and show that the cactus group action on Littelmann paths is compatible with the virtualization map defined by Pan-Scrimshaw \cite{PS18}. Our definition generalizes the group with the same name defined for the symplectic Lie algebra by the author in joint work with O. Azenhas and M. Tarighat-Feller.
