I'd like to introduce a function, which I call Y function, just because that's how its plot look like in complex plane. It can also called upsilon function, just to sound more geeky. It's defined as follow:Y(s)=ln{ζ(s) - ζ(1-s*)}
When m =1, the low slope part isn't visible.
I played around with this Y function, and found something interesting when 1 in the formula is replaced with other numbers. The plot looks simpler when s has high imaginary part.
The logarithm of a complex number z=log(r*e^(iθ)) is condensed as log(z)=log(r)+iθ, where r is the absolute value of z and θ is the argument of z. It is represented in polar coordinates.

The Riemann Hypothesis is the most notorious unsolved problem in all of mathematics. Ever since it was first proposed by Bernhard Riemann in 1859, the conjecture has maintained the status of the "Holy Grail" of mathematics. In fact, the person who solves it will win a $1 million prize from the Clay Institute of Mathematics. So, what is the Riemann hypothesis? Why is it so important? What can it tell us about the chaotic universe of prime numbers? And why is its proof so elusive?

Why is the Riemann Hypothesis hard? Just one reason (of very many): it's not an analytic question. Here are the values of zeta on the 1/2-line (where at least 40% of the zeros are, all should be) and the 4/5-line, where none should be. The latter gets arbitrarily close to 0, i.o.https://www.johndcook.com/blog/2019/11/29/near-zeros-of-zeta/
