Inflection Point of Minimally Coupled Tachyonic Scalar Field
Jaskirat Kaur, S. D. Pathak, Maxim Khlopov +1
In this paper, we investigate the behaviour of a minimally coupled tachyonic scalar field at inflection points in an accelerating universe. We consider the different expansion fact…

Unified Lagrangian for Canonical and Non-Canonical Scalar Field
Tanisha Joshi, S. D Pathak
We proposed a generalized Lagrangian for three different classes of scalar fields namely quintessence(), phantom(), and tachyonic () parameterized by . These thr…
