Abstract:

J. Kaczorowski defined the generalized Euler totient function(n,F) corresponding to a polynomial Euler product F. Let E(x,F)denote the error term in the asymptotic formula of the summatory function of(n,F). J. Kaczorowski proved that the mean square of E(x,F) has an asymptotic formula ifF satisfies GRH. We can prove a sharper asymptotic formula under GRH.
