## Interesting iterative formula that fails to converge to Riemann zeta zeros for c close to 1

Let the matrix $A$ be the lower triangular matrix defined as: $$A=\text{If } n \bmod k=0 \text{ then } \frac{1}{n^c} \text{ else } 0$$ and let the matrix $B$ be the upper triangular matrix defined as: $$B=\text{If } k \bmod … Continue reading

## Train of thought leading from the zeta function to the Möbius function

(*start Mathematica 8*) (*Start with Riemann zeta:*) Zeta[s] (*Take the logarithm:*) Log[Zeta[s]] (*Take the derivative:*) D[Log[Zeta[s]], s] Clear[s, c] (*Generalize it:*) Limit[Zeta[c] – Zeta[s]*Zeta[c]/Zeta[s + c – 1], c -> 1] (*See that Zeta[s]*Zeta[c]/Zeta[s+c-1] is the Dirichlet generating \ function … Continue reading
