摘要：
The leading divergences of the generating functional for Green functions of quark currents between one-nucleon states are calculated with heat kernel techniques. The results allow for a chiral invariant renormalization of all two-nucleon Green functions of the pion-nucleon system to O(p3) in the low-energy expansion.
