Abstract (EN):
By using new inequalities involving powers of rational functions, we give another proof of an important Spira's relation for the Riemann zeta-function vertical bar zeta(1 s)vertical bar <= vertical bar zeta(s)vertical bar in the strip 0 < Rs < 1/2, vertical bar Is vertical bar >= 12. Moreover, we establish a sufficient condition of the validity of the Riemann hypothesis in terms of the derivative of vertical bar zeta(s)vertical bar(2) with respect to Rs and conjecture its necessity.
