摘要 对U(1)场中含有Chern-Simons项的CP^1模型用变分法证明了其拓扑孤立子解的存在性.进而,又用分析的方法讨论了该解的单调性和渐近性. In this paper, applying the variational method, we proved the existence of topo- logical solitons for the CP^1 model with Chern-Simons term in U(1) field. Furthermore, we established the monotonicity and asymptotic behavior for the solutions by analytical skills.
