Séminaire de Géométrie Tropicale
Mercredi 28 janvier, 16h15 salle 1525-502
Real Young tableaux
Résumé :
I show that the tropicalization of the cluster algebra of the principal affine space for GL_n is a simplicial fan in the cone of Young tableaux.
By analogy with real roots for Kac-Moody algebras, a Young tableau is said to be real if it belongs to this fan.
Examples will be discussed.
