Inflationary scenario in Bianchi type V bulk viscous cosmological model in Saez Ballester theory

This study investigates a geometrically uniform yet directionally variant Bianchi type-V inflationary cosmic framework within a tensor-scalar gravitational theory formulated by Saez-Ballester, where the bulk viscous fluid is the source of the energy-momentum tensor. We establish a comprehensive solution by employing potential physical parameters: (i) We propose an additional relationship BC= α and B/C= β regarding metric variables. (ii) Consider ξq = k (invariant), where θ stands for the expansion scalar and ξ for the bulk viscous coefficient. We discovered that spatial volume grows with time, suggesting the model’s expansionary nature. A thorough assessment of the model’s geometrical and physical characteristics is additionally furnished.
