| 概要 | The extended $CP^N$ Skyrme-Faddeev model in (3+1) dimensions has many interesting properties. One of them is a fact that it possesses an integrable sector which appears when some constraint on derivatives of the fields is imposed. Another its significant feature is the existence of some exact solutions. Within them there is a large family of the vortex solutions having finite energy per unit length. The novelty of these solutions is the existence of the waves that propagate along the vortices and contribute to the energy density in a very nontrivial way. This contribution leeds to dependence of the energy per unit length on the mutual distance between the vortices. |
