Abstract：
In 1/N order vertex and fermion mass corrections are calculated in (2+1)dimensional chiral Gross-Neveu model.In terms of the fermion mass spectrum,derived from chiral Ward-Takahashi identities,the phase structure in 1/N order is discussed.It turns out that chiral W-T identities with composite fields are a powerful method to investigate chiral symmetry breaking and higher order corrections.
