    "abstract": "We develop a Lorenz- and gauge-invariant dynamical model for pion\nelectroproduction in the resonance region. The model is based on solving of the\nSalpeter (instantaneous) equation for the pion-nucleon interaction with a\nhadron-exchange potential. We find that the one-particle-exchange kernel of the\nSalpeter equation for pion electroproduction develops an unphysical singularity\nfor a finite value of $Q^{2}$. We analyse two methods of dealing with this\nproblem. Results of our model are compared with recent single-polarization data\nfor pion electroproduction.",
