Sharp semiclassical bounds for the moments of eigenvalues for some Schroedinger type operators with unbounded potentials

We establish sharp semiclassical upper bounds for the moments of some negative powers for the eigenvalues of the Dirichlet Laplacian. When a constant magnetic field is incorporated in the problem, we obtain sharp lower bounds for the moments of positive powers not exceeding one for such eigenvalues. When considering a Schroedinger operator with the relativistic kinetic energy and a smooth, nonnegative, unbounded potential, we prove the sharp Lieb-Thirring estimate for the moments of some negative powers of its eigenvalues.

The Thompson group F and F-separating actions

In a joined work with E. Kirchberg we study conditions ensuring that a crossed product of a C*-algebra by a discrete group is strongly purely infinite (simple or non-simple). In this (3nd) talk I give an example of an action of the Thompson group F on the real line R that is minimal and F-separating and use it to construct a non-minimal F-separating action, thus answering (in the positive) the question from my first talk on strongly purely infinite crossed product.

Strong pure infiniteness of crossed products, II
In a joined work with E. Kirchberg we study conditions ensuring that a crossed product of a C*-algebra by a discrete group is strongly purely infinite (simple or non-simple). In this (2nd) talk I will discuss some of the application of this work to specific crossed products.
