标题： Properties of some (3+1) dimensional vortex solutions of the CP^N model

摘要： 我们构造了(3+1)维CP^N模型的新一类类似涡旋的解，并讨论了它们的一些性质。 这些解是通过将二维CP^N模型中已建立的技术推广到(3+1)维得到的。 我们表明，由于这些解的总能量是无限的，它们描述了随时间变化的涡旋和反涡旋，某些配置的能量密度随时间变化。 我们还对这些涡旋的动力学做出了一些进一步的观察。 显示英文摘要

摘要： We construct new classes of vortex-like solutions of the CP^N model in (3+1) dimensions and discuss some of their properties. These solutions are obtained by generalizing to (3+1) dimensions the techniques well established for the two dimensional CP^N models. We show that as the total energy of these solutions is infinite, they describe evolving vortices and anti-vortices with the energy density of some configurations varying in time. We also make some further observations about the dynamics of these vortices.
