Title: Wavelets, Tiling and Spectral Sets Speaker: Yang Wang Affiliation: Georgia Tech. Time: Location: Abstract: A function is a wavelet in the traditional sense if is an orthonormal basis for . In the more general setting, A function in is a wavelet if is an orthonormal basis of for some set of matrices and vectors . But what are the constraints on and ? This question has surprising connection to the study of tiling and spectral sets. Title: Local Methods in General Algebra Speaker: Ágnes Szendrei Affiliation: University of Szeged Time: 4:15pm, Monday, March 3 Location: BESC 180 Abstract: During the past twenty years, a theory of localization has been developed for completely general algebraic systems. This theory has been instrumental in the solution of many problems that were previously unapproachable. For the strategy of localization to be effective, it is necessary to understand the possible minimal local structures. This requires the solution of a wide family of classification problems. In the talk I will outline the method of localization, summarize the degree to which the required classification problems have been solved, and discuss some applications. |
