(08013)Time-Periodic Solutions of the Einstein's Field Equations II: Geometric Singularities
时间: 2008-07-30 来源:数学科学研究中心In this paper, we construct several kinds of new time-periodic solutions of the vacuum Einstein's field equations whose Riemann curvature tensors vanish, keep finite or take the infinity at some points in these space-times, respectively. The singularities of these new time-periodic solutions are investigated and some new physical phenomena are discovered.
