Abstract
We consider a matrix nonlinear partial differential equation that generalizes
Heisenberg ferromagnet equation. This generalized Heisenberg ferromagnet
equation is completely integrable with a linear bundle Lax pair related to the
pseudo-unitary algebra. This allows us to explicitly derive particular
solutions by using dressing technique. We shall discuss two classes of
solutions over constant background: soliton-like solutions and quasi-rational
solutions. Both classes have their analogues in the case of the Heisenberg
ferromagnet equation related to the same Lie algebra.
