Abstract

For a proper action of a Lie group on a manifold, I will explain how to define the index of an orbital elliptic operator as an element of K-theory of the appropriate crossed product C*-algebra. The orbital index theorem is similar to the index theorem for usual elliptic operators but involves the orbital Dirac operator instead of the Dolbeault element.
