A Uniform Approach to Fundamental Sequences and Hierarchies |
|
| Authors: | Wilfried Buchholz Adam Cichon Andreas Weiermann |
| Abstract: | In this article we give a unifying approach to the theory of fundamental sequences and their related Hardy hierarchies of number-theoretic functions and we show the equivalence of the new approach with the classical one. Mathematics Subject Classification: 03D20, 03F15, 03E10. |
