- Title
Oscillating quintom scenario with time-dependent periodic deceleration parameter.

Ilyas, M.; Athar, A. R.
- Abstract
In this paper, we introduced the deceleration parameter (q) in a different manner by proposing a modern law. According to this law, we suggested a time-periodic q. Furthermore, we used this law to develop a model in which the universe oscillates with quintom matter in a four-dimensional FLRW metric background. Using this model, we obtained the oscillating Hubble parameter (H) , which remains positive. Consequently, the universe undergoes decelerating expansion and accelerating expansion periodically, avoiding singularities.
