Line-bundles on the moduli-space of G-torsors
Abstract: Over the moduli-space of G-torsors on a curve (G a semisimple simply connected split algebraic group) we construct line-bundles corresponding to arbitrary central charges. This had been previously done only in characteristic zero or for the classical groups (using determinants of cohomology and Pfaffians) and G2, but not the other exceptional groups. For E8 the remaining index is 30. The construction uses the reduction to generic Borels.
