Delzant models of moduli spaces

Abstract

For every genus we construct a smooth, complete, rational polarized algebraic variety together with an effective normal crossing divisor such that for every moduli space of semistable topologically trivial vector bundles of rank 2 on an algebraic curve of genus there is a holomorphic isomorphism , where is the Kummer variety of the Jacobian of , sending the polarization of to the theta divisor of the moduli space. This isomorphism induces isomorphisms of the spaces and .
