Joint extreme values of the Riemann zeta function at harmonic points
Qiyu Yang, Shengbo Zhao
Using the resonance method, we obtain refined estimates for joint extreme values of the Riemann zeta function at harmonic points, improving upon Levinson's 1972 results and providi…

Large values of derivatives of the Riemann zeta function on vertical homogeneous progressions
Qiyu Yang, Shengbo Zhao
In this paper, we establish lower bounds for the maximum of derivatives of the Riemann zeta function on vertical homogeneous progressions. When the real part lies within a suit…

Extreme values of derivatives of the Dedekind zeta function of a cyclotomic field
Zhonghua Li, Yutong Song, Qiyu Yang +1
In this paper, we establish a lower bound for the maximum of derivatives of the Dedekind zeta function of a cyclotomic field on the critical line. Employing a double version convol…
