Abstract

We give a term rewriting characterization of the polyspace functions. Our work follows investigations on term rewriting characterizations of some classes of (sub-) recursive functions as initiated by Cichon and Weiermann [4] and continued by Beckmann and Weiermann [1].The main novelty of this paper is a technique for reformulating recursion schemes. The aim of this technique is to provide rewriting rules which give rise to rewriting chains whose terms are suitably bounded. This bounding is crucial when dealing with computational classes with space constraints.
