Time-periodic universes
De-Xing Kong, Kefeng Liu, Ming Shen
In this letter we construct a new time-periodic solution of the vacuum Einstein's field equations whose Riemann curvature norm takes the infinity at some points. We show that this…

Time-Periodic Solutions of the Einstein's Field Equations II
De-Xing Kong, Kefeng Liu, Ming Shen
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 in…

Time-Periodic Solutions of the Einstein's Field Equations
De-Xing Kong, Kefeng Liu
In this paper, we develop a new method to find the exact solutions of the Einstein's field equations by using which we construct time-periodic solutions. The singularities of the t…
