Witryna27 lut 1999 · We look at various uniform and non-uniform complexity classes within P/poly and its variations L/poly, NL/poly, NP/poly and PSpace/poly, and look for analogues of the Ajtai-Immerman theorem which... Witryna12 lip 2014 · ABSTRACT. Matrix interpretations can be used to bound the derivational and runtime complexity of term rewrite systems. In particular, triangular matrix interpretations over the natural numbers are known to induce polynomial upper bounds on the complexity of (compatible) rewrite systems.

Witryna6 gru 2012 · A basic issue in computer science is the complexity of problems. Computational complexity measures how much time or memory is needed as a … 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.

( Immerman-Szelepscenyi Theorem ) {\sf NL} = {\sf coNL} NL = coNL . We will complete the proof of this theorem in the rest of this lesson. Non-Connectivity To prove the Immerman-Szelepscenyi Theorem, it suffices to show that there exists an {\sf NL} NL -complete language which is contained in {\sf coNL} coNL.

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.
The compression theorem is an important theorem about the complexity of computable functions. The theorem states that there exists no largest complexity class, with computable boundary, which contains all computable functions. The space hierarchy theorems are separation results that show that both deterministic and nondeterministic machines can solve more problems in (asymptotically) more space, subject to …
