The class of nonlinear evolution equations (NLEE) – gauge
equivalent to the N-wave equations related to the simple Lie algebra
are derived and analyzed. They are written in terms of
satisfying
nonlinear constraints. The
corresponding Lax pairs and the time evolution of the scattering data are
found. The Zakharov–Shabat dressing method is appropriately modified to
construct their soliton solutions.
