Large N_c in Chiral Resonance Lagrangians

Abstract

In the first part of the talk, I discussed results on the determination of the ratios of the light quark masses from large N_c chiral perturbation theory, to be described elsewhere. The following notes contain material from the second part of the talk, which concerns the implications of large N_c for resonance dominance estimates of the low energy coupling constants in chiral perturbation theory.
