Cosmological Models in Lyra Geometry: Kinematics Tests

TL;DR

This paper investigates cosmological models within Lyra geometry, analyzing observational tests like luminosity distance and look back time, revealing a universe free of Big Bang singularity and exhibiting acceleration.

Contribution

It introduces cosmological models in Lyra geometry and explores their observational consequences, including singularity-free and accelerating universe scenarios.

Findings

Universe model is free of Big Bang singularity.

Models predict an accelerating universe.

Luminosity distance and other observational tests are consistent with Lyra geometry.

Abstract

In this paper the observational consequence of the cosmological models and the expression for the neoclassical tests, luminosity distance, angular diameter distance and look back time are analyzed in the framework of Lyra geometry. It is interesting to note that the space time of the universe is not only free of Big Bang singularity but also exhibits acceleration during its evolution.
