Differential geometry is a wide domain of modern mathematics, whose significance is increasing at present. The theory of structures on manifolds is very interesting topic of modern differential geometry. The differential geometric aspects of submanifolds of manifolds with certain structures are vast and very fruitful fields for Riemannian geometry. The book is intended to serve the researchers and post graduate students at various Universities who are interested in the field of differential geometry. "Structures On Differentiable Manifolds and Its Submanifolds" discusses the theory of various structures on differentiable manifolds and its submanifolds.The global treatment of coordinate free method is followed to derive the results. The lucid presentation of the contents will certainly serve the purpose for which it is meant.
