This book aims to study on a Riemannian manifold admitting a new special type semi-symmetric metric connection. Firstly, it contains a brief knowledge on semi-symmetric metric connection. It represents a special type of semi-symmetric metric connection on a Riemannian manifold. In the last section of this book, it is considered conformally flat manifolds with this new type semi-symmetric metric connection. On this manifold, some theorems are proved. Sections 3 and 4, are published as a paper in European Journal of Pure and Applied Mathematics, 4(2), 152-161, (2011). In this book,...
