Abstract

In this note, by introducing a new variant of the resonator function, we give an explicit version of the lower bound for $\log |L(\sigma ,\chi )|$ in the strip $1/2<\sigma <1$ , which improves the result of Aistleitner et al. [‘On large values of $L(\sigma ,\chi )$ ’, Q. J. Math. 70 (2019), 831–848].
