Schreiber Synthetic quantum theory in higher cohesive toposes

This summer I will be giving a talk at the 2013 CMS summer meeting (Halifax, June 2013) in the session Progress in higher categories.

    Synthetic quantum theory in higher cohesive toposes

on Higher geometric prequantum theory in the context of differential cohomology in a cohesive topos.


There are two traditional mathematical formalizations of quantum physics via quantization: “algebraic deformation quantization” and “geometric quantization”. I discuss how the latter has a natural axiomatic (“synthetic”) formulation in those higher toposes which are equipped with two adjoint triples of idempotent higher modalities – a joint refinement of what Lawvere had called “synthetic differential geometry” and “cohesion”. This yields synthetic re-derivations of classical and of more recent results in geometric quantization, and lifts them from quantum mechanics to local (“extended”) quantum field theory in higher dimension. I close by indicating examples of Chern-Simons type field theories. The example in dimension 2 recovers C-star algebraic deformation quantization as its “holographic dual”; the example in dimension 3 holographically recovers twisted equivariant K-theory. The example in dimension 7 relates to current questions in non-perturbative string theory.
