Symplectic right keys -- Type C Willis' direct way
João Miguel Santos
It is known that the right key of a Kashiwara-Nakashima tableau can be computed using the Lecouvey-Sheats symplectic jeu de taquin. Motivated by Willis' direct way of computing typ…

Symplectic keys and Demazure atoms in type C
João Miguel Santos
We compute, mimicking the Lascoux-Schützenberger type A combinatorial procedure, left and right keys for a Kashiwara-Nakashima tableau in type C. These symplectic keys have a simil…
