Abstract
A general technique for obtaining dispersion relations in the mass variable is proposed. The method is used in order to translate the low-energy theorems valid for “mathematical pions” of zero four-momentum into physically meaningful expressions for real pions. Our procedure is explicitly applied to low-energy pion scattering and electroproduction of pions on nucleons.
