ANALYSIS OF BIANCHI TYPE-V COSMOLOGICAL MODEL WITH TIME-VARYING GRAVITATIONAL AND COSMOLOGICAL CONSTANTS

In this work, we investigate the evolution of an anisotropic Bianchi Type-V cosmological model in the presence of time-varying gravitational and cosmological constants, and . The Einstein field equations are formulated by incorporating variable and , allowing for a more general description of cosmic evolution. The cosmic fluid is assumed to consist of perfect fluid, whose equation of state is employed to model the matter distribution in the universe. Exact solutions of the field equations are obtained under suitable assumptions relating the expansion scalar and anisotropy parameters. By considering suitable relations among the metric potentials and adopting a variable-decoupling approach, exact solutions of the modified field equations are obtained.
