Adiabatic Limit of Calderon Projector on Manifold with Cylindrical End

Abstract: For a Riemannian manifold with a cylindrical end, consider a Dirac-type operator that is asymptotically product type with the generalized Atiyah-Patodi-Singer boundary condition on any finite portion of the cylinder. In the present work we consider the problem of constructing the Calderon projector in this setting and studying the adiabatic limit of it along the cylindrical end. As a consequence, we extend a result of Nicolaescu on adiabatic limits of Cauchy data spaces. The proof leverages resolvent and its estimates in the framework of the b-calculus needed for the construction of the Calderon projector corresponding to our Dirac-type operator.
