The Calderon projection over C* algebras
arXiv:1307.1968
Abstract
We construct the Calderon projection on the space of Cauchy datas for a twisted Dirac operator in the Mischenko--Fomenko pseudodifferential calculus for operators acting on bundles of finitely generated --Hilbert modules on a compact manifold with boundary. In particular an invertible double is constructed generalizing the classical result.
