Oscillating flat FRW dark energy dominated cosmology from periodic functional approach. (English) Zbl 1213.83147

Summary: I discuss the modification of Einstein’s theory of general relativity based on a periodic functional approach. In this new approach, a corrected periodic gravitational coupling constant arises and plays the role of periodic damping term acting on the theory. It is found that it is achievable to have an oscillating universe dominated by dark energy and expanding accelerating in time.
