ON THE ZEROS OF THE EISENSTEIN SERIES FOR Γ*0(5) AND Γ*0(7)
ON THE ZEROS OF THE EISENSTEIN SERIES FOR Γ*0(5) AND Γ*0(7)
We locate almost all of the zeros of the Eisenstein series associated with the Fricke groups of level 5 and 7 in their fundamental domains by applying and extending the method of Rankin and Swinnerton-Dyer (On the zeros of Eisenstein series. Bull. London Math. Soc. 2 (1970), 169-170). We also …
