论文摘要
已经发现磁场具有对重力作用的固有能力。文献中提出的一个重要问题是，磁场的存在是否可以改变重力崩溃的动力学并防止奇异性的最终形成。在这种情况下，尚未对崩溃的不均匀模型进行探索。在目前的工作中，我们研究了磁场在不均匀圆柱体对称模型进化中的作用。我们使用基于Raychaudhuri方程的方法进行此类分析。我们表明，磁场很有可能在这些模型中避免重力崩溃。
Magnetic fields have been found to have an inherent capability of acting against gravity. An important question posed in the literature is whether presence of a magnetic field can alter the dynamics of a gravitational collapse and prevent the final formation of a singularity. Inhomogeneous models of collapse have not been explored significantly in this context. In the present work we investigate the role of magnetic fields in the evolution of inhomogeneous cylindrically symmetric models. We use an approach based on the Raychaudhuri equation for such an analysis. We show that it is quite possible for the magnetic field to avert the gravitational collapse in these models.
