### BOUNCING COSMOLOGY IN MODIFIED THEORIES OF GRAVITY

#### Mishra B., Agrawal A., Tripathy S.K.

In this study, we describe a $$f(R)$$ gravity theory-based bouncing cosmological model of the universe. The flat FLRW space-time were used to determine the model’s dynamical behaviour. At the bouncing epoch, the geometrical parameters exhibit singularity behaviour. The parameters of the scale factor have a significant impact on the bouncing behaviour.

Keywords: Clifford algebra, Dirac Equation, Feynman checkerboard.
