Résumé: On the occasion of Laci Babai's approaching 60th birthday we are holding a conference with the title "Combinatorics, Groups, Algorithms, and Complexity" at the Ohio State University, Columbus, Ohio. The date of the meeting is March 21-25, 2010 (Sunday-Thursday), with an opening social event Saturday evening (March 20).

The talks will highlight interconnections between the areas in the title. It is our hope that the conference will inspire new links and further cross-fertilization.

Résumé: 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.

Résumé: This workshop, sponsored by AIM and the NSF, will be devoted to the outer automorphism group of the free group, Out(F); in particular, its geometry and its inherent asymmetry.
