摘要
通过2维和4维温度弦模型研究暗能量玻色子星的质量和物态参量,推导高亏格黎曼面上的玻色弦自由能,获得引力场方程和dilaton暗能量场方程的表达式,给出玻色子星的质量和物态参量的推导过程.另外,还分析和比较了不同时空中计算结果所具有的特点.
In this paper,the mass and state parameters of dark energy boson star are studied according to two dimensional and four dimensional temperature string model,and the Bose string free energy on high genus Riemann surface is derived.The expressions of gravitational field equation and the dilaton dark energy field equation are obtained,and the derivation process of mass and state parameters for the boson star are given.Moreover,the characteristics of the calculation results in the different timespace are analyzed and compared.
