Extreme values of quadratic Dirichlet -functions with prime-related moduli

Zikang Dong, Weijia Wang, Hao Zhang +1

In this paper, we show a new lower bound for extreme values of quadratic Dirichlet -functions with prime-related moduli, which generalizes the work of Darbar and Maiti in 2025,…

Extreme values of quadratic Dirichlet -functions

Zikang Dong, Weijia Wang, Hao Zhang +1

In this paper, we investigate extreme values of quadratic Dirichlet -functions at the central point. We provide new extreme values of as is large, which im…

Extreme values of derivatives of Dirichlet -functions

Xinghua Cui, Zhifeng Peng, Yutong Song +1

In this paper, we establish lower bounds for extreme values of derivatives of Dirichlet \(L\)-functions in the range \(1/2<σ<1\). Compared with the work of Aistleitner, Mahatab, M…

Some Omega results for Dirichlet -functions

Qiyu Yang, Shengbo Zhao

Motivated by the first author's earlier work in 2024, we use the resonance method to establish some Omega results for Dirichlet -functions, extending the previous results.

Joint extreme values of Dirichlet (L)-functions and their logarithmic derivatives

Shengbo Zhao

In this paper, we establish joint extreme values of Dirichlet (L)-functions and their logarithmic derivatives using the resonance method. Our results extend previous work of Aistle…

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…
