Are there known zeros of the Zeta function off the line 1/2?












4














I've been doing research in information theory that had some superficial connections to the Zeta function, since I was making use of logarithms of complex numbers.



In short, we'd be looking at the Zeta function using values of s produced by powers of the logarithm function:



$zeta(log^n (-1)/x).$



I noticed several zeros for n = 6:

But, I don't know enough about this topic to be sure that this is actually interesting, since I know that at least some of the zeros of this function are considered "trivial". Nonetheless, I thought I'd share this in case some of you found it interesting and had insights.

    $zeta(-2n)=0$ are "trivial" zeros off the line $1/2$, see this post.

    There are no known zeros of $zeta(s)$ that don’t occur at a negative even integer (these are the trivial zeros) or have real part $sigma=frac12$. The Riemann Hypothesis states that any zero with real part between $0$ and $1$ will in fact have real part exactly $frac12$.

First of all, when plotted, only the real part of your graph crosses zero. Secondly, the only known zeroes of the zeta function off of the ${1 over 2} + atimes i$ line are the negative even integers, each of which is a zero. These are called trivial zeroes. The Riemann Hypothesis states that all other zeroes lie on that magic line. It is known that at least 40% of them lie there, and none off of it have ever been found.
