Abstract

Quantum LL_\infty algebras are a generalization of LL_\infty algebras with a scalar product and with operations corresponding to higher genus graphs. We construct a minimal model of a given quantum LL_\infty algebra via the homological perturbation lemma and show that it's 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 and this effective quantum LL_\infty algebra.
