Complex powers of abstract pseudodifferential operators

Abstract

Under suitable assumptions, we show that the abstract pseudodifferen\-tial operators introduced by Connes and Moscovici possess complex powers that belong to this class of operators. We analyse several spectral functions obtained via the (super)trace including the zeta function and the heat trace. We present examples showing that the analysis is explicit and tractable.

Key words: Complex powers, abstract pseudodifferential operators, noncommutative residue, zeta function, heat trace, index theory.
