The Ritz and harmonic Ritz values are approximate eigenvalues, which can be computed cheaply within the FOM and GMRES Krylov subspace iterative methods for solving non-symmetric linear systems. They are also the zeros of the residual polynomials of FOM and GMRES, respectively. In this paper we show
Using the norm residue symbol and a reciprocity law of Artin and Hasse, we determine the conductors of Kummer extensions of the form K( p n a, `n)ÂK(`n) for any unramified extension K of Q p , element a # K\*, and primitive p n th root of unity `n. We are able to do this without more recent and gene
