Two methods to prove the Riemann Hypothesis are presented. One is based on the modular properties of Θ (theta) functions and the other on the Hilbert–Polya proposal to find an operator whose spectrum reproduces the ordinates ρn (imaginary parts) of the zeta zeros in the critical line: sn = 1 2 +iρn. A detailed analysis of a one-dimensional Dirac-like operator with a potential V (x) is given tha...
