# Bounds for the imaginary part of the non-trivial zeros of the Riemann zeta function.

Let $\rho_{k}=\beta_{k}+i\gamma_{k}$ the $k-th$ non-trivial zero of the Riemann zeta funcion. We consider only the zeros with $\gamma_{k}>0$ . Then we have$$\gamma_{1}=14.13...$$ $$\gamma_{2}=21.02...$$ etc. so it seems that holds $$\gamma_{k}>k.$$ I checked the first 100 zeros and it seems to be true. Is it known? I haven't found anything like that on the internet.

The statement is false. Recalling that $N\left(T\right)$ is the number of non-trivial zeros of the Riemann zeta function with imaginary part $0<\gamma\leq T$, we know that holds $$N\left(T\right)\sim\frac{T}{2\pi}\log\left(T\right)$$ then we have $$k=N\left(\gamma_{k}\right)\sim\frac{\gamma_{k}}{2\pi}\log\left(\gamma_{k}\right)$$ and so$$\log\left(k\right)\sim\log\left(\gamma_{k}\right)$$ hence $$\gamma_{k}\sim\frac{2\pi k}{\log\left(k\right)}$$ as $k\rightarrow\infty .$
