- Abstract
This study explores the Bianchi type-V cosmological model with in the frame work of general relativity, featuring a perfect fluid governed by the polytropic equation in Lyra’s Geometry, expressed p = αρ + kρn, as proposed at [1]. We considered the case representing phantom universe for(1 + α + kρn−1) 6 0, k < 0 , where ρ increases with the radius a(t). The role of Lyra;s Geometry has been discussed/ The solution to Einsteins field equation have been derived, providing insights into the physical and cosmological attributes of this particular model
