Study of rip cosmological models in f(T, B) gravity

The rip cosmological models of the universe have been presented in this paper in f(T, B) gravity, where T and B respectively denote the torsion scalar and boundary term. Three models pertaining to Little Rip, Big Rip, and Pseudo Rip are shown, and their geometrical and dynamical parameters are analyzed. The violation of strong energy conditions in each case has also been shown. The behaviour of the equation of state parameter in the case of the Little Rip model and the Pseudo Rip model shows phantom-type behaviour but remains very close to the \(\Lambda \) $\mathrm{\Lambda }$ CDM line. In all these accelerating models, the avoidance of singularity scenarios has been observed. The geometrical parameters for all the rip models have been investigated in each category. It has been observed that this study is in alignment with the current observational data studies.
