Global existence for equivalent nonlinear special scale invariant damped wave equations

Abstract Full Text(HTML) Related Papers Cited by
  • In this paper we give the notion of equivalent damped wave equations. As an application we study global in time existence for the solution of special scale invariant damped wave equation with small data. To gain such results, without radial assumption, we deal with Klainerman vector fields. In particular we can treat some potential behind the forcing term.
