Abstract
The recent results by Bowick and Rajeev on the relation of the geometry of DiffS 1/S 1 and string quantization in ℝd are extended to a string moving on a group manifold. A new derivation of the curvature formula (−26/12m 3+1/6m)δ n, −m for the canonical holomorphic line bundle over DiffS 1/S 1 is given which clarifies the relation of that bundle with the complex line bundles over infinite-dimensional Grassmannians, studied by Pressley and Segal.
