On automorphisms of semistable <i>G</i>-bundles with decorations
Abstract We prove a rigidity result for automorphisms of points of certain stacks admitting adequate moduli spaces. It encompasses as special cases variations of the moduli of G -bundles on a smooth projective curve for a reductive algebraic group G . For example, our result applies to the stack of …
