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, Langevin equation and generalizations

  3. linear evolutionary differential equations (often for operator functions) of the form dy/dt=Lyd y/ d t = L y where LL is a linear operator not involving differentiating with respect to time is sometimes called a master equation in some contexts
