There have been several recent interesting talks at the KITP in Santa Barbara as part of their program this semester on Mathematical Structures in String Theory<\/a>. Last week Greg Moore gave a beautiful talk on Mathematical Aspects of Fluxes<\/a>. It’s a sad commentary on the state of the field that he felt it necessary to begin his talk by apologizing that the work he was describing didn’t seem to have anything useful to say about the Landscape.<\/p>\n

This week Graeme Segal spoke about On the Locality of the Statespace of Quantum Field Theory<\/a>. He is trying to understand the right way to axiomatize the way in which the Hilbert space of a QFT depends on the boundary of space-time in a local fashion. In his talk he worked out things for the case of a free scalar on an arbitrary manifold. Also this week, Peter Teichner<\/a> and Stephan Stolz<\/a> spoke on their work on generalized cohomology and QFT, motivated by trying to understand the relation of elliptic cohomology and conformal field theory. Teichner gave the first part of the talk<\/a> on Tuesday, Stolz gave the second part<\/a> on Thursday. For more about their work, see some earlier comments of mine<\/a>, their paper What is an elliptic object?<\/a>, and an earlier survey talk by Teichner at the KITP<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
