Analytical Study of Bouncing Cosmology in f(Q,C) Gravity With Generalized Infrared Cutoffs

ABSTRACT In this work, we have studied bouncing cosmology in gravity framework. This gravity theory is an extension of gravity where a boundary term is also included. We have considered holographic fluid with generalized infrared cut‐offs to drive the bounce. For some chosen forms of , we have discussed the bouncing behavior with scale factors derived from the IR cutoffs of some generalized forms of holographic fluid considered as bouncing fluid. We have checked the null‐energy condition for our models and also discussed the second law of thermodynamics in this setup. The analysis shows that the models can produce bouncing solutions, which are mathematically consistent and can give possible explanation to the early universe without an initial singularity. The study also indicates that gravity with generalized cut‐offs may be useful to understand cosmic evolution beyond standard .
