玻色弦在推广GPS背景场中的运动

THE MOTIONS OF BOSONIC STRING IN THE GENERALIZED GPS BACKGROUND FIELD

本文讨论了玻色弦在推广GPS背景场中的运动.结果表明玻色弦的轨迹为双锥曲线,形状由弦能量E^2与弦的等效质量μ~2决定.本文还考虑了磁单极催化"Winders"湮灭的可能性,并导出其条件.同时,本文导出了玻色弦在一般弯曲时空中的运动方程,为广义Lorentz方程、

It is dicussed that the motions of bosonic string in the generalized GPS background field, in this paper, its orbits are exactly ellipticil, parabolic and hyperbolic for E^2<μ~2, E^2=μ~2 and E^2>μ~2 respectively. The possibility of the monopoles catalyse the decay or annihilation of winders is also dicussed and condition is pointed out. The motion equation of bosonic string in the curved space-times is obtained, it is a general Lorentz equation.
