February 16, 2020

Even if we do not always agree on some mathematical formulations, I think that Christof Born has nevertheless written an exciting, number-mystical essay! Book: The Secret of Ishango

General Riemann spectrum

(Inverse) Riemann spectrum shows resonances at prime numbers

February 13, 2019

Here is a comprehensive description of the topic in the last two posts about the sum formula. It is already well-known as the “Riemann spectrum of prime numbers”. The authors are Geoffrey Glover, Grant Keane and Rita Post. Link: https://people.uwec.edu/mbirika/M395_Riemann/The_Riemann_Spectrum_of_the_Prime_Numbers.pdf

Plot of the Inverse Riemann spectrum: resonances of prime numbers

February 11, 2019

Here is a plot of the Inverse Riemann Spektrum in the range 10 – 100. The first 2000 zeros of Riemann’s Zeta-function have been evaluated. Prime numbers and their powers have been marked on the x-axis (big / small red circles). For Zooming into the picture please click on it.

Sum formula shows nice resonances at primes and prime powers

February 4, 2019

The following sum formula which shows very impressive peaks at the positions of primes and their powers. The formula displays the ‘Inverse Riemann spectrum’ of the non trivial roots of the zeta function:   Here the sum goes over the imaginary parts of the non trivial zeros of Riemanns Zeta function, taking nmax zeros. The…
