We give an index formula for a class of Dirac operators coupled with unbounded potentials. More precisely, we study operators of the form P := = D + V, where =

The chapters on Clifford algebra and differential geometry can be used as an introduction to the topics, and are suitable for senior undergraduates and graduate

In the first edition of this book, simple proofs of the Atiyah-Singer Index Theorem for Dirac operators on compact Riemannian manifolds and its generalizations
