WitrynaLe théorème d'Immerman-Szelepcsényi est un théorème d' informatique théorique, et notamment de la théorie de la complexité, démontré en 1987 indépendamment par Neil Immerman et Róbert Szelepcsényi, et qui leur a valu d'obtenir conjointement le prix Gödel en 1995. Une version simplifiée de ce théorème est NL = co-NL. WitrynaTheorem. ( 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.

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.
