The second edition of this highly praised textbook provides an introduction to tensors group theory & their applications in classical & quantum physics Both intuitive & rigorous it aims to demystify tensors by giving the slightly more abstract but conceptually much clearer definition found in the math literature & then connects this formulation to the component formalism of physics calculations New pedagogical features such as new illustrations tables & boxed sections as well as additional "invitation" sections that provide accessible introductions to new material offer increased visual engagement clarity & motivation for students Part I begins with linear algebraic foundations follows with the modern component-free definition of tensors & concludes with applications to physics through the use of tensor products Part II introduces group theory including abstract groups & Lie groups & their associated Lie algebras then intertwines this material with that of Part I by introducing representation theory Examples & exercises are provided in each chapter for good practice in applying the presented material & techniques Prerequisites for this text include the standard lower-division mathematics & physics courses though extensive references are provided for the motivated student who has not yet had these Advanced undergraduate & beginning graduate students in physics & applied mathematics will find this textbook to be a clear concise & engaging introduction to tensors & groups Reviews of the First Edition" Physicist Nadir Jeevanjee has produced a masterly book that will help other physicists understand those subjects tensors & groups as mathematicians understand them From the first pages Jeevanjee shows amazing skill in finding fresh compelling words to bring forward the insight that animates the modern mathematical view With compelling force & clarity he provides many carefully worked-out examples & well-chosen specific problems Jeevanjee&s clear & forceful writing presents familiar cases with a freshness that will draw in & reassure even a fearful student This is a masterpiece of exposition & explanation that would win credit for even a seasoned author"-Physics Today" Jeevanjee&s text is a valuable piece of work on several counts including its express pedagogical service rendered to fledgling physicists & the fact that it does indeed give pure mathematicians a way to come to terms with what physicists are saying with the same words we use but with an ostensibly different meaning The book is very easy to read very user-friendly full of examplesand exercises & will do the job the author wants it to do with style"-MAA Reviews
