(2+1)-Dimensional Cosmological Model of the Universe through GTR

This book focuses more on the lower dimension of the Cosmological model of the universe through the General Theory of Relativity. In this book, we have to drive and solve the different line elements with different equations of state in the (2+1)-Dimensional model. This book is more precise for lower-dimensional problems. We have solved cosmological modal in the modified theory of relativity as well as in another alternative theories of relativities.
