## Abstract Some basic results for Dirichlet series __ψ__ with positive terms via log‐convexity properties are pointed out. Applications for Zeta, Lambda and Eta functions are considered. The concavity of the function 1/__ψ__ is explored and, as a main result, it is proved that the function 1/__ζ__
