Complexity classes

Nonelementary problem

In computational complexity theory, a nonelementary problem is a problem that is not a member of the class ELEMENTARY. As a class it is sometimes denoted as NONELEMENTARY. Examples of nonelementary problems that are nevertheless decidable include: * the problem of regular expression equivalence with complementation * the decision problem for monadic second-order logic over trees (see S2S) * the decision problem for term algebras * satisfiability of W. V. O. Quine's fluted fragment of first-order logic * deciding β-convertibility of two closed terms in typed lambda calculus * reachability in vector addition systems; it is Ackermann-complete.

Matthias Baaz: Fast cut elimination in intuitionistic logic

The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: In this lecture we provide an elementary procedure to eliminate prenex cuts in LJ without v. (For LK without v the elimination of prenex cuts is nonelementary). As coroll
