Pushnitski's -invariant and Schrödinger operators with embedded eigenvalues
Nurulla Azamov
In this note, under a certain assumption on an affine space of operators, which admit embedded eigenvalues, it is shown that the singular part of the spectral shift function of any…
Spectral averaging for trace compatible operators
Nurulla Azamov, Fyodor Sukochev
In this note the notions of trace compatible operators and infinitesimal spectral flow are introduced. We define the spectral shift function as the integral of infinitesimal spectr…
Infinitesimal spectral flow and scattering matrix
Nurulla Azamov
In this note the notion of infinitesimal scattering matrix is introduced. It is shown that under certain assumption, the scattering operator of a pair of trace compatible operators…
Operator integrals, spectral shift and spectral flow
N. A. Azamov, A. L. Carey, P. G. Dodds +1
We present a new and simple approach to the theory of multiple operator integrals that applies to unbounded operators affiliated with general von Neumann algebras. For semifinite v…
