A new kind of solutions of the Einstein's field equations with non-vanishing cosmological constant
De-Xing Kong, Kefeng Liu, Ming Shen
In this paper we construct a new kind of solutions of the Einstein's field equations with non-vanishing cosmological constant, which possess some interesting physical properties. T…

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…
