%0 Journal Article %T A Predicative Harmonization of the Time and Provable Hierarchies %A Salvatore Caporaso %J Computer Science %D 2006 %I arXiv %X A decidable transfinite hierarchy is defined by assigning ordinals to the programs of an imperative language. It singles out: the classes TIMEF(n^c) and TIMEF(n_c); the finite Grzegorczyk classes at and above the elementary level, and the \Sigma_k-IND fragments of PA. Limited operators, diagonalization, and majorization functions are not used. %U http://arxiv.org/abs/cs/0609130v1
