Electromagnetic duality and the Langlands programme

Triangular Seminar David Olive (University of Swansea)

15:00 City U.
room CM375

A recent paper by Kapustin and Witten synthesises ideas from pure mathematics and quantum field theory that have been developing independently for more than thirty years. Thus the Langlands programme, itself a unification scheme in mathematics, relates to electromagnetic duality and the topological twisting of supersymmetry. An attempt will be made to explain these ideas.
