Tilted and Non Tilted C-Field Cosmological Models

TL;DR

This paper explores tilted and non-tilted homogeneous plane symmetric C-field cosmological models, analyzing their solutions, physical parameters, and universe evolution stages based on a specific creation field dependent on time.

Contribution

It presents new solutions for tilted and non-tilted C-field cosmological models using a method by Narlikar and Padmanabhan, with assumptions linking pressure and density.

Findings

Different stages of universe evolution are characterized in non-tilted models.

Physical parameters' behaviors are analyzed over cosmic time.

Deterministic models are derived with specific pressure-density relations.

Abstract

Tilted and non tilted homogeneous plane symmetric C-field cosmological models are investigated. Using the method of Narlikar and Padmanabhan [4], the solutions have been presented when the creation field C is function of time t only. To get the deterministic model, we have assumed the supplementary condition between pressure and density . The behaviour of different stages of the universe has been studied in non tilted models. We have also investigated the behaviours of some physical parameters.
