Kapranov's noncommutative geometry

Mikhail Kapranov introduced a framework of noncommutative algebraic geometry, which could be interpreted as the study of infinitesimal thickenings of commutative schemes within bigger noncommutative spaces. The idea is to look at commutative schemes together with a sheaf of nilpotent noncommutative O-algebras; the formalism utilizes the filtrations relating to the commutator expansions from Maslov-Feynman calculus.
