Precize Differential Geometry (Pbi. U.)


The present book is the culmination of honest and sincere efforts on the part of the author to meet the requirements of students who opt for mathematics at the Post graduation level.

The entire subject matter has been arranged in a simple, systematic, graded, lucid and exhaustive manner to meet the various needs of all types of learners. Each chapter begins with some definitions followed by theorems with complete proofs and solved problems so that the study leads to perfect clarity and understanding. A large number of notes and remarks have been added for a better understanding of the subject.
