Query: The delta invariant of curves on rational surfaces II: Poincar\'e series
  and topological aspects   In this article we study abstract and embedded invariants of reduced curve
germs via topological techniques. One of the most important numerical analytic
invariants of an abstract curve is its delta invariant. Our primary goal is to
develop delta invariant formulae for curves embedded in rational singularities
in terms of embedded data. The topological machinery not only produces
formulae, but it also creates deep connections with the theory of (analytical
and topological) multivariable Poincar\'e series.
