Abstract

The 1/N-c expansion of the heavy baryon Isgur-Wise functions is discus sed. Because of the contracted SU(2N(f)) light quark spin-flavor symme try, the universality relations among the Isgur-Wise functions of Lamb da(b)-->Lambda(c) and Sigma(b)()-->Sigma(c)(*) are valid up to the or der of 1/N-c(2).
