Abstract
We have presented the Big Rip singularity in [Formula: see text] gravity with tilt congruences and creation field. We have solved the field equations by considering a conformally flat universe and the condition [Formula: see text], where [Formula: see text] is a constant. The solutions of the field equations have also been investigated by using the method of [J. V. Narlikar and T. Padmanabhan, Phys. Rev. D 32, 1928 (1985)] in which the creation field [Formula: see text] is a function of time [Formula: see text]. Some geometric aspects of the model are also discussed by using MATLAB.
期刊介绍:
This letters journal, launched in 1986, consists of research papers covering current research developments in Gravitation, Cosmology, Astrophysics, Nuclear Physics, Particles and Fields, Accelerator physics, and Quantum Information. A Brief Review section has also been initiated with the purpose of publishing short reports on the latest experimental findings and urgent new theoretical developments.
