Regularized Traces and K-theory Invariants of Parametric Pseudodifferential Operators


This expository article outlines our recent construction of invariants of relative K-theory classes of multi-parameter dependent pseudodifferential operators, which recover and generalize Melrose’s divisor flow. These are ‘higher’ divisor flows, that are obtained by pairing relative K-theory classes with relative cyclic cocycles manufactured out of… (More)
