摘要：

Low-energy theorems are derived for pion-nucleon scattering from dispersion relations and crossing symmetry. The presence of low-lying pion-nucleon resonances is taken into account. The relations obtained are different from the low-energy theorems obtained from current algebra and the hypothesis of partially conserved axial-vector current. © 1969 The American Physical Society.
