WitrynaMid. This article has been rated as Mid-priority on the project's priority scale. "In its general form the theorem states that NSPACE = co-NSPACE. In other words, if a nondeterministic machine can solve a problem, it can solve its complement problem (with the yes and no answers reversed) in the same asymptotic amount of space." WitrynaProof sketch []. The theorem can be proven by showing how to translate any nondeterministic Turing machine M into another nondeterministic Turing machine that …

Witrynav. t. e. 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. WitrynaIn computational complexity theory, the Immerman–Szelepcsényi theorem states that nondeterministic space complexity classes are closed under complementation. It was proven independently by Neil Immerman and Róbert Szelepcsényi in 1987, for which they shared the 1995 Gödel Prize.

An important issue in circuit complexity is uniformity, i.e., the question if a ﬁnite description of an inﬁnite family of circuits exists, and if yes, how complicated it is to obtain it. Immerman’s Theorem holds both non-uniformly, i.e., under no requirements on the constructability of the circuit family, as well
