从一个物质场存在于体中的膜世界的动力学出发,当膜世界上的非均匀尘埃/广义暗辐射和体中的非均匀暗辐射的动力学都被认为是精确的动力学坍缩解时,体度规和膜附近的黑弦解被推广。在分析膜上均匀暗辐射坍缩球的非均匀静态外表面的基础上,研究了相应的黑弦弯曲视界,以及膜附近的5D体度规.此外,通过对物理软奇点的分析,发现在模型中暗辐射参数取适当值时,黑弦和体块随时间的演化更有规律。
From the dynamics of a brane-world with matter fields present in the bulk, the bulk metric and the black string solution near the brane are generalized, when both the dynamics of inhomogeneous dust/generalized dark radiation on the brane-world and inhomogeneous dark radiation in the bulk as well are considered -- as exact dynamical collapse solutions. Based on the analysis on the inhomogeneous static exterior of a collapsing sphere of homogeneous dark radiation on the brane, the associated black string warped horizon is studied, as well as the 5D bulk metric near the brane. Moreover, the black string and the bulk are shown to be more regular upon time evolution, for suitable values for the dark radiation parameter in the model, by analyzing the physical soft singularities.
