Abstract

We study “forbidden” conductors, i.e. numbers $q>0$ satisfying algebraic criteria introduced by J. Kaczorowski, A. Perelli and M. Radziejewski, that cannot be conductors of $L$-functions of degree $2$ from the extended Selberg class. We show that the set of forbidden $q$ is dense in the interval $(0,4)$, solving a problem posed in [6]. We also find positive points of accumulation of rational forbidden $q$.
