WebJul 20, 2024 · In this work, we are aiming to explore the cosmological bouncing scenarios in symmetric teleparallel gravity (i.e., f ( Q) gravity). This manuscript is organized as follows: in Sect. 2, we briefly discuss the gravitational formalism for f ( Q) gravity. In Sect. 3, we present the energy conditions. Then, we discuss different types of bouncing ... WebIn this paper, we studied the strong, the weak, the null, and the dominant energy conditions for f (Q) gravity, working with a perfect fluid matter distribution. The actual accelerating phase our Universe passes through, constraints that the strong energy condition should be violated.
