Abstract

We investigate the size of sets of computable functions using category-theoretic methods (in the sense of the Baire Category theorem). Constructive definitions of no-where dense and meagre set are given and applied to several problems. In particular we apply it to subrecursive degree structures and to a comparison of the power of deterministic and nondeterministic time bounded oracle machines.
