摘　　要：By making use of the C-mapping topological current theory and the decomposition of gauge potential theory, we investigate the （2＋1）-dimensional skyrmion excitations in ferromagnets. We also discuss the branch processes of these skyrmions and the generation and annihilation of skyrmion-antiskyrmion pairs.
