2010 TALBOT WORKSHOP: TWISTED K-THEORY AND LOOP GROUPS May 23-29, 2010 Breckenridge, Colorado This posting announces the 2010 Talbot Workshop, Twisted K-theory and Loop Groups, mentored by Constantin Teleman. The workshop will constitute a weeklong retreat with talks and organized discussions during the mornings and evenings; the afternoon schedule will be kept clear for informal discussions and collaborations. The workshop will generally focus on understanding the relationship between the representation theory of a loop group LG and the equivariant twisted K-theory of G. Specifically, talks will develop the geometric approach to the representation theory of loop groups, K-theory and its twisted variant, basic computations of K-theory, Dirac operators and the families index theorem, extended topological field theories and Chern-Simons theory, conformal field theory and the WZW model, and recent work on extending Chern-Simons and gauged Gromov-Witten theory. The workshop discussions will have an expository character and will be aimed at graduate students and junior faculty interested in this area. Further information about the workshop will become available at: http://math.mit.edu/talbot This website also contains information about the past Talbot workshops: Fukaya categories (mentored by Paul Seidel), Affine Lie algebras and chiral structures (mentored by Dennis Gaitsgory), Topological modular forms (mentored by Michael Hopkins), Automorphisms of manifolds (mentored by Michael Weiss), Geometric Langlands (mentored by David Ben-Zvi), and Geometric models of elliptic cohomology (mentored by Stephan Stolz). If you are interested in participating or would like to receive further information about the workshop, please go to math.mit.edu/talbot. We may be able to subsidize participants' travel expenses. Please note that the number of participants will be strictly limited for space reasons.
