dc.descriptionIn the framework of the low energy chiral Lagrangian renormalization group equations for the couplings are investigated up to order p^6 -- as well for SU(2)xSU(2) as for SU(3)xSU(3) chiral symmetry. Infrared attractive fixed points for ratios of O(p^4) couplings are found, which turn out to agree with the values determined from experiment in a surprisingly large number of cases. Infrared attractive fixed line solutions for O(p^6) couplings in terms of O(p^4) couplings and among O(p^6) couplings are determined.
