AIS Representation Theory (2007) - Speakers and Syllabus

  • Representation theory of groups is one of the most beautiful subjects in mathematics which finds applications to many other subjects including Physics and Chemistry, besides being of fundamental importance to numerous areas of mathematics. The aim of this summer school will be to offer a first course in representation theory of finite as well as compact groups. After developing the general theory, the school will try to emphasize representation theory of specific groups such as SU(2), SL(2,F_q), and the symmetric groups, which forms building blocks for representation theory of more complicated groups. There will be some lectures on applications of representation theory to Number theory, as well as combinatorics, and perhaps an example from the work of the Fields medalist Okounkov's work. There will be some lectures too to bring out the historical perspective of the subject.
