The validity of these all relations is considered for a number of soliton models in 2+1- and 3+1-dimensions.Talk given at the XVIII International Workshop on High Energy Physics and Field Theory, Protvino, Russia, June 1995. 8 pages, LaTeXHigh Energy Physics - TheoryLorentz-Covariant Analysis of a Quantum Solitontext
