Spectral flow and the unbounded Kasparov product
Jens Kaad, Matthias Lesch
We present a fairly general construction of unbounded representatives for the interior Kasparov product. As a main tool we develop a theory of C^1-connections on operator * modules…

A local global principle for regular operators in Hilbert C*-modules
Jens Kaad, Matthias Lesch
Hilbert C*-modules are the analogues of Hilbert spaces where a C*-algebra plays the role of the scalar field. With the advent of Kasparov's celebrated KK-theory they became a stand…

Perturbation of Sectorial Projections of Elliptic Pseudo-differential Operators
Bernhelm Booss-Bavnbek, Guoyuan Chen, Matthias Lesch +1
Over a closed manifold, we consider the sectorial projection of an elliptic pseudo-differential operator A of positive order with two rays of minimal growth. We show that it depend…
