Poincaré families and automorphisms of principal bundles on a curve (Pre-published version)

Hoffmann, Norbert; Biswas, Indranil (Elsevier, 2009)

Let C be a smooth projective curve, and let G be a reductive algebraic group. We give a necessary condition, in terms of automorphism groups of principal G-bundles on C, for the existence of Poincaré families parameterized ...
