Tilted Two Fluids Cosmological Models with Variable G and {\Lambda} In General Relativity

TL;DR

This paper develops tilted two-fluid cosmological models within General Relativity, incorporating variable gravitational and cosmological constants, analyzing their physical behaviors and implications for the universe's evolution.

Contribution

It introduces a new class of tilted two-fluid models with variable G and Λ, assuming constant parameters s and n, and explores their physical properties.

Findings

Models exhibit specific behaviors of physical parameters.

Variable G and Λ influence cosmological evolution.

Tilted models provide insights into universe dynamics.

Abstract

Tilted two fluids cosmological models with variable G and {\Lambda} In General Relativity are presented. Here one fluid is matter field modelling material content of the universe and another fluid is radiation field modelling the cosmic microwave background (CMB). The tiltedness is also considered .To get the deterministic model, we have assumed a supplementary condition where s and n are constants. We have also discussed the behaviours of some physical parameters.
