Let $a>0$ be a fixed real number, and let $Q$ denote the first quadrant of the complex plane. A function has monotonic zeros in $Q$ when its zeros there, listed by increasing real…

Let $Q$ denote the first quadrant of the complex plane, and for $N\in\mathbb N$ let $\Xi_N(z)$ be the truncation of Riemann's uniformly convergent series for the Riemann $\Xi$-func…
