Book Title: Combinatorial Number Theory
Editor: Landman, B; Nathanson, MB; Nesetril, J; Nowakowski, RJ; Pomerance, C; Robertson, A
Abstract:
For a positive integer k let phi(k) be the k-fold composition of the Euler function phi. In this paper, we study the size of the Set {phi(k)(n) <= x} as x tends to infinity.
For a positive integer k let phi(k) be the k-fold composition of the Euler function phi. In this paper, we study the size of the Set {phi(k)(n) <= x} as x tends to infinity.
Keywords: Iterations of Euler's function; applications of sieve methods
