This book is composed of two parts: Part I (Chaps. I through 3) is an introduction to tensors and their physical applications, and Part II (Chaps. 4 through 6) introduces group theory and intertwines it with the earlier material. Both parts are written at the advanced-undergraduate/beginning graduate level, although in the course of' Part II the sophistication level rises somewhat. Though the two parts differ somewhat in flavor,l have aimed in both to fill a (perceived) gap in the literaiure by connecting
the component formalisms prevalent in physics calculations to the abstract but more conceptual formulations found in the math literature. My firm beliefis that we need to see tensors and groups in coordinates to get a sense of how they work, but also need an abstract formulation to understand their essential nature and organize our thinking about them.
