A Prime-Divisor Function

J. Knopfmacher
1973 Proceedings of the American Mathematical Society  
This note studies the asymptotic mean values over arithmetical progressions, the general distribution of values, and the maximum order of magnitude, of a certain natural prime-divisor function of positive integers. Consider the multiplicative arithmetical function ß defined by /S(l) = l and ß(n) = axa2 ■ ■ ■ ocr if n=p\lp%% ■ ■ ■ plr (pt prime, oct>0). Kendall and Rankin [2, p. 199] pointed out that this function has the finite mean value y 1 V * * £(2)£(3) , 0", lim -> ß(n) =-= 1.943 • • •
