LOW-ENERGY SUM-RULES AND LARGE-N-C CONSISTENCY CONDITIONS

The large-N-c consistency conditions for axial-vector and isovector magnetic couplings of pions to baryons are discussed from the point of view of low-energy current-algebra sum rules (Adler-Weisberger, Cabibbo-Radicati). Tn particular, we show how the result that ratios of axial-vector and isovector magnetic coupling constants get corrections only at the order 1/N-c(2) follows from the N-c-counting of appropriate cross sections. This counting is performed using various approaches at the quark and hadronic level. Other implications of our method are also presented.
