討論有一類在Gr(n,N) σ-模型中(3+1)維的漩渦解。這些解是(3+1)維CP^N σ-模型漩渦解的推廣。此漩渦解和Noether核和拓撲荷有關聯。
A class of vortex solutions of the Gr(n,N) Grassmannian σ-Model in (3+1) dimensions are presented. These solutions may be regarded as the generalization of the vortex solutions of the CP^N model [1]. The energy density of the vortices are related to the Noether charge and topological charge.
