Complete Logarithmic Sobolev Inequalities (CSLI) and Ricci Curvature

Haojian Li (UIUC)

Abstract: First we would continue Eddie's talk and start with how the connection on a G-bundle induces a connection on the associated bundle naturally. Then a brief introduction about the quantum information will be included. We would focus on formulating the CLSI problem today and show that the CLSI constants depend on the lower bound of Ricci curvature. If time permits, we would also apply our machinery to Hormander system.

Some properties of alpha fidelities.

Xiaojing Yan

Abstract: The alpha fidelities constitute a family of information measures that generalize the well-known fidelity, inheriting many of its properties. In the first half of the talk, we will introduce some natural properties for quantum alpha fidelities, including data-processing inequalities and monotonicity and so on. In the second, we will calculate the quantum α-fidelity between unitary orbits.

The Dixmier Trace

Haojian Li (UIUC)

Abstract: We will construct so-called exotic traces on the space of bounded operators on a Hilbert space, the so called Dixmier traces. In the long run we are interested in geometric applications of Connes' Dixmier trace calculus.
