Zeros of Dedekind zeta functions under GRH
Assuming GRH, we prove an explicit upper bound for the number of zeros of a
Dedekind zeta function having imaginary part in . We also prove a
bound for the multiplicity of the zeros.Comment: Some misprints corrected, simplified proof for a lemma. This version

Explicit versions of the prime ideal theorem for Dedekind zeta functions under GRH
Let \psi_\K be the Chebyshev function of a number field \K. Under GRH we
prove an explicit upper bound for |\psi_\K(x)-x| in terms of the degree and
the discriminant of \K. The new bound improves significantly on previous
known results.Comment: Some misprints corrected. This is the final version which will appear
in Mathematics of Computatio
Explicit zero density theorems for Dedekind zeta functions
This article studies the zeros of Dedekind zeta functions. In particular, we
establish a smooth explicit formula for these zeros and we derive an effective
version of the Deuring-Heilbronn phenomenon. In addition, we obtain an explicit
bound for the number of zeros in a box.Comment: 24 page
