The motion of relativistic strings in curved space-times
Chun-Lei He, De-Xing Kong
This paper concerns the motion of a relativistic string in a curved space-time. As a general framework, we first analyze relativistic string equations, i.e., the basic equations fo…
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…
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…
