Monotonicity of the imaginary part of the Riemann $\xi$ function in the region $S$
Abstract
This paper proves that the imaginary part of the Riemann $\xi$ function is strictly monotonic with $b$ in the region $S = \{t|t=a+bi,\ 0\leq a \leq 9.508,\ -1/2<b<1/2\}$. That leads to Im($\xi$)=0 being true only when $b=0$ in $S$.
