Choice of the uncritical manifold for dilute polymer solutions
  We discuss the dependence of the results of renormalized perturbation theory for dilute polymer solutions on the choice of the uncritical manifold where the perturbation series are evaluated. Special emphasis is given to the influence of polydispersity corrections on the results of one and two loop calculations. For monodisperse solutions we establish that after a Borel resummation the dependence on the choice of the uncritical manifold decreases when higher orders of the expansion are taken into account.
