We have studied string cosmology in higher-dimensional cylindrically symmetric model which is in the Kaluza–Klein spacetime. Some of the solutions show a nonsingularity of the spacetime.

String Source

Field equations in the presence of cosmic string source are obtained in Barber's second self-creation theory of gravitation (Gen. Relativ. Gravit.14, 117 (1982)) with the aid of Einstein–Rosen cylindrically symmetric metric. A static vacuum model and a nonstatic exact string cosmological model are presented which represents Reddy string (Astrophys. Space Sci.286, 365 (2003)) in self-creation theory. Some physical and kinematical properties of the model are also discussed.
