The Riemann Hypothesis for Dirichlet $L$ Functions (1308.6431v1)

Abstract: This paper studies the connections between the zeros and their distribution functions for two particular Dirichlet $L$ functions: the Riemann zeta function, and the Catalan beta function, also known as the Dirichlet beta function. It is shown that the Riemann hypothesis holds for the Dirichlet beta function $L_{-4}(s)$ if and only if it holds for $\zeta (s)$- a particular case of the Generalized Riemann Hypothesis.
