Noncommutativity from spectral flow

open access: yes, 2007
We investigate the transition from second to first order systems. This transforms configuration space into phase space and hence introduces noncommutativity in the former.

Cohomology of classes of symbols and classi cation of traces on corresponding classes of operators with non positive order

open access: yes, 2010
This thesis is devoted to the classification issue of traces on classical pseudo-differential operators with fixed non positive order on closed manifolds of dimension $n>1$.

On Spectral Invariants of Dirac Operators on Noncommutative Tori and Curvature of the Determinant Line Bundle for the Noncommutative Two Torus [PDF]

open access: yes, 2015
We extend the canonical trace of Kontsevich and Vishik to the algebra of non-integer order classical pseudodifferntial operators on noncommutative tori. We consider the spin spectral triple on noncommutative tori and prove the regularity of eta function at zero for the family of operators $e^{th/2}De^{th/2}$ and the couple Dirac operator $D+A$ on ...
