Abstract:
In 1983, S. M. Voronin obtain an analytic continuation to the entire complex plane for some twists of $L$-functions associated with holomorphic modular forms on $\mathrm{SL}(2,Z)$. In this paper, we extend Voronin's result to $L$-functions of degree $2$ from the extended Selberg class.
Keywords:$L$-function, holomorphic modular form, the group $\mathrm{SL}(2,Z)$, meromorphic function, quadratic irrational, Selberg class, Dirichlet coefficients.
