Abstract

Nicolas inequality we deal can be written as eγloglog Nx lt; \dfracNxφ(Nx) , where x≥ 2, Nx denotes the product of the primes less or equal than x, γ is the Euler constant and φ is the Euler totient function. We see that verification of such an inequality depends on the sign of the big-O function in the Mertens estimate for the sum of reciprocals of primes that. Then we analyze the sign of such an error term.
