Abstrakt:
We establish that the Hitchin connection is a perturbation of the L2 connection. We notice that such a formulation of the Hitchin connection does not necessarily require the manifold in question possessing a rigid family of Kähler structures. We then proceed to calculate the asymptotic expansion of general perturbations of the L2-connection, and see when under certain assumptions such perturbations are at and projectively at. During the calculations we also found an asymptotic expansion of the projection operator $\pi_\sigma^{(k)}$ which projects onto the holomorphic sections of the k-th tensor of prequantum line bundle.
