Query: Dynamic First Order Wave Systems with Drift Term on Riemannian Manifolds   An abstract first order differential equation of hyperbolic type with drift
term on a Riemannian manifold is considered. For proving its well-posedness,
transmutator and commutator relations are needed, which are studied in a
general functional analytic setting.
