Trace inequalities and spectral shift

, 2009
We derive monotonicity and convexity inequalities for traces of operator functions defined on self-adjoint elements of a semi-finite von Neumann algebra.

Asymptotics of large eigenvalues for a class of band matrices

, 2012
We investigate the asymptotic behaviour of large eigenvalues for a class of finite difference self-adjoint operators with compact resolvent in $l^2$

Perturbation Theory for the Quantum Time-Evolution in Rotating Potentials

, 2002
The quantum mechanical time-evolution is studied for a particle under the influence of an explicitly time-dependent rotating potential. We discuss the existence of the propagator and we show that in the limit of rapid rotation it converges strongly to ...

On Cayley Identity for Self-Adjoint Operators in Hilbert Spaces [PDF]

, 2011
We prove an analogue to the Cayley identity for an arbitrary self-adjoint operator in a Hilbert space. We also provide two new ways to characterize vectors belonging to the singular spectral subspace in terms of the analytic properties of the resolvent ...
