In BV-BRST formalism the plain Lagrangian density of a given Lagrangian field theory is accompanied by an auxiliary Lagrangian density depending on auxiliary fields such as ghost fields and antifields, such that the local antibracket with the sum yields the BV-BRST differential
which models the derived critical locus inside the homotopy quotient modeled by the BRST complex of the theory.
