nLab Maslov-Feynman calculus

Maslov-Feynman calculus (Feynman-Maslov commutator expansion) is an expansion in terms of commutators of expressions in associative algebras. It has been pioneered independently by Richard Feynman in quantum field theory and by V. P. Maslov in the analysis of operators (and, in particular, WKB method).

Kapranov used it in “Kapranov's noncommutative geometry based on commutator expansions”.
