Abstract
We consider a family of approximations of the Dedekind zeta function \(\zeta _K(s)\) of a number field \(K/\mathbb {Q}\). Weighted \(L^2\)-norms of the difference of two such approximations of \(\zeta _K(s)\) are computed. We work with a weight which is a compactly supported smooth function. Mean square estimates for the difference of approximations of \(\zeta _K(s)\) can be obtained from such weighted \(L^2\)-norms. Some results on the location of zeros of a family of approximations of Dedekind zeta functions are also derived. These results extend results of Gonek and Montgomery on families of approximations of the Riemann zeta-function.
