Unveiling Crystal Embeddings: New Perspectives on String Polytopes and Atomic Decompositions
Lara Bossinger, Jacinta Torres
We present n-1 different embeddings of string polytopes of type A. We characterize their compatibility with the crystal structure on the string polytopes, and formulate a conjectur…

Atoms and charge in type
Leonardo Patimo, Jacinta Torres
We construct atomic decompositions for crystals of type and define a charge statistic on them, thus providing positive combinatorial formulas for Kostka-Foulkes polynomials…

The virtual cactus group and Littelmann paths
Jacinta Torres
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 defin…
