摘要： 本文介绍了在存在完全非均匀磁场的情况下，标量引力扰动线性理论的系统处理方法。 分析是在同步规范和共形牛顿规范中进行的。 假设宇宙等离子体由冷暗物质、重子、光子和中微子组成。 讨论了在非均匀磁场存在下，各种粒子流体变量以及玻尔兹曼-爱因斯坦方程耦合系统的超视界初始条件问题。 紧耦合近似对于玻尔兹曼层次结构被扩展到包括引力磁场所处的情况。 显示英文摘要

摘要： This paper introduces a systematic treatment of the linear theory of scalar gravitational perturbations in the presence of a fully inhomogeneous magnetic field. The analysis is conducted both in the synchronous and in the conformally Newtonian gauges. The cosmological plasma is assumed to be composed of cold dark mattter, baryons, photons, neutrinos. The problem of super-horizon initial conditions for the fluid variables of the various species and for the coupled system of Boltzmann-Einstein equations is discussed in the presence of an inhomogeneous magnetic field. The tight coupling approximation for the Boltzmann hierarchy is extended to the case where gravitating magnetic fields are included.
