Abstract
The study of numerical stability of algorithms for computing with
polynomials and matrices over archimedian fields like R and C
constitutes an entire branch of numerical analysis. The analogous
problems over Qp have received far less attention. In this talk I will
outline some number theoretic questions in which these problems arise,
and describe joint work with Xavier Caruso in which we propose a general
methodology for approaching them in practice.
