The Radial Wave Operator in Similarity Coordinates

Mathematical Physics 2010-02-24 v2 math.MP

Abstract

We present a rigorous functional analytic setting to study the radial wave equation in similarity coordinates. As an application we analyse linear stability of the fundamental self--similar solution of the wave equation with a focusing power nonlinearity.
