New zero-free regions for Dedekind zeta-functions at small and large ordinates

Sourabhashis Das, Swati Gaba, Ethan Simpson Lee +2

Given a number field $L\ne \mathbb{Q}$, we obtain new and explicit zero-free regions for Dedekind zeta-functions of $L$, which refine the previous works of Ahn--Kwon, Kadiri, and…
