nLab master equation

Especially in physics there are some types of equations that in their subfield are called master equations. Examples include the following:

  1. in BV-BRST formalism the classical master equation is the condition that the refinement of an action functional to a function on its derived critical locus squares to 0 with respect to a certain graded Poisson-bracket. The quantum master equation is a deformation of this equation. See at BV-BRST formalism for details on all this.

  2. in statistical mechanics
