International Journal of Theoretical Physics Aims and scope Submit manuscript

Abstract

We investigate the solitons in the CP N model in terms of the decomposition of gauge potential. Based on the φ-mapping topological current theory, the charge and position of solitons is determined by the properties of the typical component. Furthermore, the motion and the bifurcation of multi-soliton is discussed. And the knotted solitons in high dimension is explored also.
