and 0 < e < 2 is the modulus of convexity of X. The best results so far about the relationship between normal structure and the modulus of convexity of X are that for any Banach space X either 6(1) > 0 or 6(3/2) > 1/4 implies X has normal structure. We generalize the above results in this paper to p
## 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__
