In this paper,we construct several kinds of new time-periodic solutions of the vacuum Einstein’s field equations whose ......

In this paper,we develop a new algorithm to find the exact solutions of the Einstein’s field equations.Time-periodic so......

In this work, the authors considered the periodic optimal control problem of Fitzhugh-Nagumo equation. They firstly prov......

The compressible Navier-Stokes equations driven by a time-periodic external force are considered in this article. We est......

We show existence of time-periodic supersonic solutions in a finite interval, after certain start-up time depending on t......
