Emeritus Professor Floyd Williams co-edited a research monograph, "A window into zeta and modular physics," with Professor Klaus Kirsten of Baylor University. The book, which is published Cambridge University Press, contains lectures and research articles on zeta functions, modular forms, and vertex operator algebras, with various applications to physics, including black holes and conformal field theory. It is part of the distinguished MSRI (Mathematical Sciences Research Institute, Berkeley) series (volume 57). Besides the lectures of Kirsten and Williams, this volume also contains articles by former graduate students, Dr. Shabnam Beheshti and Dr. Jennie D'Ambroise.

Professor Panos Kevrekidis attended the American Physical Society March Meeting in Portland, and then was invited to participate on the Frontiers of Nonlinear Waves Conference in Tucson, AZ in honor of V.E. Zakharov's 70th birthday At both meetings, Kevrekidis presented his recent work on dark solitons and vortices in Bose-Einstein condensates combining theory, computations and experiments.

Assistant Professor HongKun Zhang gave the Geometry Seminar at the Department of Mathematics at Washington University St. Louis on March 26, speaking on: "Spectral gap for deterministic and random billiards." She was also invited to be one of the plenary speakers at Eastern Illinois University for "the Annual Geometry, Dynamics and Topology Day" on March 27.

On February 15, Professor Richard S. Ellis gave a colloquium talk in the Department of Mathematics at Oregon State University in Corvallis. His talk was an introduction to the theory of large deviations entitled "From Large Deviations to Statistical Mechanics: What Is the Most Likely Way for an Unlikely Event To Happen?" On February 18 Richard gave a talk at the University Convocation at Willamette University in Salem in which he discussed how Buddhist meditation can help alleviate the suffering caused by physical and emotional pain. He has a forthcoming book on this topic: "Blinding Pain, Simple Truth: Changing Your Life Through Buddhist Meditation."

February 2010

Prof. Panos Kevrekidis delivered the Mathematics Colloquium at Drexel on January 14, as well as the Physics Colloquium at Amherst College on February 11. In these talks, Panos discussed the recent work of his group on granular crystals, nonlinear optics of layered media and multi-component Bose-Einstein condensates.

On February 3, Prof. John Staudenmayer gave a talk "Novel analytical techniques for physical activity assessment" at the National Cancer Institute National Institute of Health in Bethesda, MD.

January 2010

Professor Paul Hacking gave a talk entitled Smoothing Surface Singularities via Mirror Symmetry at the MSRI workshop Tropical Structures in Geometry and Physics, which took place during the period November 30 - December 4, 2009. A video of the talk is available at http://www.msri.org.

Professor Panos Kevrekidis had a busy fall. Panos was one of the principal speakers at the interdisciplinary workshop on periodic oscillations that took place in Granada, Spain during the period October 20-24, 2009.
