摘要
Rankin proved that a specific family of Poincare series (Gk(z, 1))k & GE;24 which are cusp forms have all their finite zeros on the unit circle of the standard fundamental domain F for the action of SL(2, Z) on the complex upper half-plane H. In this article, we show that these finite zeros of Gk(z, 1) and those of Gk+12(z, 1) interlace on fe & iota;& theta; : & theta; & ISIN; (7r/2, 27r/3)}.& COPY; 2023 Elsevier Inc. All rights reserved.
