STUDIES ON GRAVITATIONAL FIELD EQUATIONS AND IMPORTANT RESULTS OF RELATIVISTIC COSMOLOGY

Exploring the universe's origin, evolution, and ultimate fate, this book delves into constructing mathematical models based on Einstein's theory of gravitation and its modifications. It presents six chapters focused on spatially homogeneous isotropic and anisotropic cosmological models within various modified gravitational theories. The research aims to compare these models with contemporary observations to better understand the universe's shape, physics, and origins, offering significant insights into relativistic cosmology.
