Toric orbifolds associated to Cartan matrices

Published 12 Oct 2011 in math.AG | (1110.2761v4)

Abstract: We investigate moduli stacks of pointed chains of projective lines related to the Losev-Manin moduli spaces and show that these moduli stacks coincide with certain toric stacks which can be described in terms of the Cartan matrices of root systems of type A. We also consider variants of these stacks related to root systems of type B and C.
