The aim of this book is to make the subject easier to understand. This book provides clear concepts, tools, and techniques to master the subject -tensor, and can be used in many fields of research. Special applications are discussed in the book, to remove any confusion, and for absolute understanding of the subject. In most books, they emphasize only the theoretical development, but not the methods of presentation, to develop concepts. Without knowing how to change the dummy indices, or the real indices, the concept cannot be understood. This book takes it down a notch and simplifies the topic for easy comprehension.FeaturesProvides a clear indication and understanding of the subject on how to change indicesDescribes the original evolution of symbols necessary for tensorsOffers a pictorial representation of referential systems required for different kinds of tensors for physical problemsPresents the correlation between critical conceptsCovers general operations and concepts
