Dec 12, Katya Krupchyk, University of HelsinkiColloquium, 458 Campbell Hall, 9:30am. Resolvent estimates for elliptic operators and their applications.
Abstract: More than 25 years ago, Kenig, Ruiz, and Sogge established uniform $L^p$ resolvent estimates for the Laplacian in the Euclidean space. Taking their remarkable estimate as a starting point, we shall describe more recent developments concerned with the problem of controlling the resolvent of elliptic self-adjoint operators in $L^p$ spaces in the context of a compact Riemannian manifold. Here some new interesting difficulties arise, related to the distribution of eigenvalues of such operators. Applications to inverse boundary problems and to the absolute continuity of spectra for periodic Schr\"odinger operators will be presented as well.
Our former colleague Eugene R. (Gene) Wilson passed away on August 21. Gene was an alumnus of UAB (BS 1977 and MA 1979) and later, from 1983 to his retirement in 2003, the Director of the Mathematics Resource Center (a precursor of today's MLL). Click here for more information.

- Prof. Nandor Simanyi proved a fifty-year-old conjecture of Ya. G. Sinai, the "Boltzmann-Sinai Ergodic Hypothesis", which states that any classically interacting hard sphere system in a box with periodic boundary conditions is ergodic (chaotic). This result is an important building block in the theoretical foundations of statistical physics. The paper may be found here.
