Abstract

Let $\chi_4$ be the non-principal Dirichlet character mod $4$ and $L(s,\chi_4)$ be the Dirichlet $L$-function associated with $\chi_4$, and put $R(s):= s 4^{s} L(s+1,\chi_4) + \pi L(s-1,\chi_4)$. In the present paper, we show that the function $R(s)$ has the Riemann's functional equation and its zeros only at the negative even integers and complex numbers with real part $1/2$. We also give other $L$-functions that have the same property.
