确定势下 SO（2）暗物质宇宙模型场方程求解初探

摘要

The effective Lagrangians expression of SO(2) dark matter model under the flat R -W spacetime is given, and the SO(2) dark matter model field equation and the zero order approximate solution of the situation for a given certain potential V(Φ) is concretely solved, meanwhile, the expression of the energy density ρΦ, the pressure PΦand other parameter of the scalar field is discussed .%　　本文首先给出了在平直R－W时空背景下SO（2）暗物质模型的有效拉氏量表达式，其次对于给定的确定的势V（Φ）求得SO（2）暗物质模型场方程并具体求解了场方程的零级近似解，同时给出了能量密度ρΦ、压强PΦ以及方程中各个参数的表达式。
