Note on large quadratic character sums

Zikang Dong, Yutong Song, Ruihua Wang +1

In this article, we investigate the conditional large values of quadratic Dirichlet character sums. We prove an Omega result for quadratic character sums under the assumption of th…

Large zeta sums

Zikang Dong, Weijia Wang, Hao Zhang

In this article, we investigate the behaviour of values of zeta sums $\sum_{n \leq x} n^{i t}$ when $t$ is large. We show some asymptotic behaviour and Omega results of zeta sums, whic…
