Summation of the euler function values over numbers of the form p − 1
Tóm tắt
An asymptotic formula is proved for the sum of values of the Euler function on numbers of the form p − 1 not exceeding x. The order of the remainder of the asymptotics corresponds to the modern bound for zeros of the zeta function.
