On the L-infinity description of the Hitchin map
Document info: Pages 13, Figures 0.
Recently, E. Martinengo obtained results on obstructions to deformations of Higgs pairs by describing an L-infinity morphism inducing the Hitchin map. In this note we show that analogous results hold for principal G-Higgs bundles. Moreover, we show that the L-infinity morphism is a 'global analogue' of a Lie-algebraic construction.
