Large values of logarithmic derivatives of quadratic Dirichlet -functions

Zikang Dong, Haidong Li

In this article, we apply the resonance method to derive conditional Omega results for logarithmic derivatives of quadratic Dirichlet -functions. We improve a previous result of…

On derivatives of zeta and -functions near the 1-line

Zikang Dong, Yutong Song, Weijia Wang +1

We study the conditional upper bounds and extreme values of derivatives of the Riemann zeta function and Dirichlet -functions near the 1-line. Let be a fixed natural numb…

Large zeta sums

Zikang Dong, Weijia Wang, Hao Zhang

In this article, we investigate the behaviour of values of zeta sums when is large. We show some asymptotic behaviour and Omega results of zeta sums, whic…

Structure of large quadratic character sums

Zikang Dong, Weijia Wang, Hao Zhang

In this article, we study the distribution of large quadratic character sums. Based on the recent work of Lamzouri~\cite{La2022}, we obtain the structure results of quadratic chara…

On Large Values of

Zikang Dong, Bin Wei

We investigate the extreme values of the Riemann zeta function . On the 1-line, we obtain a lower bound evaluation $$\max_{t\in[1,T]}|ζ(1+ıt)|\ge {\rm e}^γ(\log_2T+\log_3T+c)…

On the Distribution of large values of

Zikang Dong

We investigate the distribution of large values of the Riemann zeta function in the strip $1/2<\re s<1$. For any fixed $\re s=σ\in(1/2,1)$, we obtain an improved distributio…
