32nd Summer Conference on Topology and Its Applications


For a lecture in the Topology+Algebra and Analysis section, the subject of locally compact groups appears particularly fitting: Historically and currently as well, the structure and representation theory of locally compact groups draws its methods from each of theses three fields of mathematics. Nowadays one might justifiably add combinatorics and number theory as sources. The example of a study of a class of locally compact groups called “near abelian,” undertaken by W. Herfort, K. H. Hofmann, and F. G. Russo, may be used to illustrate the liaison of topological group theory with this different areas of interest. Concepts like the compact Hausdorff “Chabauty space” attached to each locally compact group, or the “scalar multiplication” of periodic locally compact abelian groups can serve as guiding moments in contemplating this diversity.
