Fredholm Analysis of Dirac Operators on Lorentzian Manifolds with
Spacelike Boundary
We consider globally hyperbolic manifolds with spacelike boundary consisting of compact Cauchy hypersurfaces. In this talk, I shall review the Fredholm theory of Dirac operators with the Atiyah-Patodi-Singer boundary condition. The essentials of Fourier integral operators pertinent to this analysis will also be recalled.
