Abstract

The development of a dynamical model for investigating the nucleon resonances using the reactions of meson production from \pi N, \gamma N, N(e,e'), and N(\nu,{\it l}) reactions is reviewed. The results for the \Delta (1232) state are summarized and discussed. The progress in investigating higher mass nucleon resonances is reported.
