It must be realized that the functional μ ( inf ) appearing in Ref. 3 is equal to - ( g^2/ 2 ) Q_CSG. 7-S. V. Manakov, Zh. Eksp. Teor. Fiz. 67, 543 (1974) [Sov. Phys.

We thank Professor H. de Vega for pointing out to us the correct expression (9) for the charge of the MT solitonThe soliton dynamics in the complex sine-Gordon equation, massive Thirring model, and sine-Gordon equation are shown to be closely related.engjournal articlehttp://dx.doi.org/10.1103/PhysRevD.31.3293http://journals.aps.orgopen access51-73Astronomy & astrophysicsPhysicsParticles & fieldsFísica-Modelos matemáticosFísica matemática
