Large values of quadratic character sums revisited
Zikang Dong, Ruihua Wang, Weijia Wang +1
We study large values of quadratic character sums with summation lengths exceeding the square root of the modulus. Assuming the Generalized Riemann Hypothesis, we obtain a new Omeg…

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…
