Elliptic boundary problems have enjoyed interest recently, espe cially among C* -algebraists and mathematical physicists who want to understand single aspects o
Two classes of local elliptic boundary conditions for the Dirac operator are studied: one posed on a family of even-dimensional spin manifolds and one posed on
In this work, an index theorem is proved for arbitrary families of elliptic boundary value problems for Dirac operators and a surgery formula for the index of a
