Extreme residues of Dedekind zeta functions

Abstract

In a family of $S_{d+1}$-fields ($d=2,3,4$), we obtain the true upper and lower bound of the residues of Dedekind zeta functions except for a density zero set. For $S_5$-fields, we need to assume the strong Artin conjecture. We also show that there exists an infinite family of number fields with the upper and lower bound, resp.

The definition of $L(s,\rho )$ is given in the introduction. The proof of Proposition 4.3 is revised
