Combinatorics and formal geometry of the master equation (1205.5970v1)
Published 27 May 2012 in math.QA, hep-th, and math.AT
Abstract: We give a general treatment of the master equation in homotopy algebras and describe the operads and formal differential geometric objects governing the corresponding algebraic structures. We show that the notion of Maurer-Cartan twisting is encoded in certain automorphisms of these universal objects.
