Titre Denseness of g-vector cones from marked surfaces
Horaire14:00 à 15:00

A triangulation of marked surfaces induces a Jacobian algebra. We study g-vector cones associated with its tau-tilting modules. We determine the closure of the union of g-vector cones associated with all tau-tilting modules. It is equal to the whole space. Our main ingredients are laminations, their shear coordinates and their asymptotic behavior under Dehn twists. The same result holds for gentle algebras by using their geometric realization.
