Combinatorics and formal geometry of the master equation [PDF]
Joseph Chuang, Andrey LazarevWe 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.View original: http://arxiv.org/abs/1205.5970
