I was searching for a fancy-looking mathematical expression that vaguely resembles my name “Leon” and came up with the somewhat meaningless “$\zeta\in o(\pi)$”. One might interpret it as describing a relation between the asymptotic growth rates of the Riemann zeta function and the Prime-counting function.
The latter is unbounded while the Riemann zeta function asymptotically tends towards one $\zeta(x) \xrightarrow{x\to\infty} 1$. Thus $\zeta$ obviously grows slower than $\pi$ so $\zeta\in o(\pi)$.
