[en] Single-soliton solutions of the relativistic model of a complex scalar field with self-action are obtained. The situation is discussed, when nonlinearity depends on field derivatives. The model consideration is confined by the two-dimensional space-time case. The problem of transverse and longitudinal stability of the solutions in the linear approximation of perturbation theory is investigated
