四维方程(□-m^2)Φ=λΦ~3的非拓扑孤粒子解

NONTOPOLOGICAL SOLITON SOLUTIONS OF KLEIN-GORDON TYPE EQUATION(□-m^2)Φ=λΦ~3 IN FOUR SPACE-TIME DIMENSIONS

非拓扑性孤粒子解与拓扑性孤粒子解的根本区别是,它不需要有简并真空态,一切的解,不论有无孤粒子,在无穷远处都有同样的边界条件.本文着重讨论四维方程(□-m^2)Φ=λΦ~3的精确的非拓扑孤粒子解及其物理意义.

Exact nontopological soliton solutions of equation(□-m^2)Φ=λΦ~3 in four or lower space-time dimensions are obtained.The physical interpretation of these solutions is also discussed.
