Ktheory, Representation Theory and Automorphic Forms
September 1112, Sheffield
Organized by Paul Mitchener, Roger Plymen and Haluk Sengun
Automorphic forms are central objects in modern number theory with fascinating connections to many other parts of mathematics. The cohomological interpretation of modular forms, going back to works of Eichler and Shimura in the 1950's, is a key approach to automorphic forms that relates the cohomology of arithmetic manifolds to automorphic forms through representation theory of Lie groups.
The recent paper [BS16] studies the Ktheory/Khomology of certain C*algebras ("arithmetic C*algebras") that naturally arise from arithmetic manifolds. The results obtained in this paper raise the possibility of an approach to automorphic forms via the Kgroups of arithmetic C*algebras, akin to the wellknown cohomological approach to automorphic forms. Our meeting will bring together a small group of experts
in Ktheory, representation theory and automorphic forms in order to
develop these ideas.
