"QUANTUM L-INFINITY ALGEBRAS, BATALIN-VILKOVISKY QUANTIZATION AND THE HOMOLOGICAL PERTURBATION LEMMA?"
Branislav Jurco (Charles University, Praga)
Abstract:
Quantum homotopy Lie algebras are a generalization of homotopy Lie algebras with a scalar product and with operations corresponding to higher genus graphs. We construct a minimal model of a given quantum homtopy
Lie algebra via the homological perturbation lemma, and show that it is given by a Feynman diagram expansion, computing the effective action in the finite- dimensional Batalin-Vilkovisky formalism.
We also construct a homotopy between the original homotopy Lie algebra and this effective quantum homotopy Lie algebra.
