Talk by Prof. Dr. Ezra Getzler

A cyclic L-infinity algebra is a shifted symplectic formal derived stack. Using a new geometric approach to homological perturbation theory, we construct a shifted symplectic form on the associated derived stack. (This is a derived analogue of the correspondence between Lie algebroids and Lie groupoids.)
