This textbook presents a lucid and unified description of Abstract algebra at a level which can be easily understood by the students who posses reasonable mathematical aptitude and abstract reasoning. The book provides an example oriented, less heavily symbolic approach to abstract algebra and the text emphasizes specifics such as rings, integral domains and field, polynomial rings, vector spaces, matrices and linear transformations etc. the book concludes with the coverage of eigen values and eigen vectors of matrices. The text of the book is prepared according to the new pattern of UGC by keeping in view the requirement of the students of several universities and colleges.

This book is written to meet the requirements of undergraduate students of several Universities. The topics included in the text fully cover the entire course prescribed by several Universities. (Jacket)
