On the action of the modular group on spin structures over closed surfaces in relation to theta functions and string amplitudes:
On the canonical/geometric quantization of D=3 Chern-Simons theory:
Early argument that the RR-field flux density-expressions for D-brane charge are of the form of Chern characters on topological K-theory, leading to the K-theory classification of D-brane charge:
