Immerman theorem

WitrynaThe Immerman-Vardi theorem states that PTIME (or P) is precisely the class of languages that can be described by a sentence of First-Order Logic together with a fixed-point operator, over the class of ordered structures. The fixed-point operator can be either least fixed-point (as considered by Immerman and by Vardi), or inflationary fixed-point.

In quantum field theory, the LSZ reduction formula is a method to calculate S -matrix elements (the scattering amplitudes) from the time-ordered correlation functions of a quantum field theory. It is a step of the path that starts from the Lagrangian of some quantum field theory and leads to prediction of measurable quantities.
