WebPreface Riemannian, symplectic and complex geometry are often studied by means of solutions to systems of nonlinear di erential equations, such as the equa-tions of geodesics, min Let be the determinant line bundle with . For every connection with on , there is a unique spinor connection on i.e. a connection such that for every 1-form and vector field . The Clifford connection then defines a Dirac operator on . The group of maps acts as a gauge group on the set of all connections on . The action of can be "gauge fixed" e.g. by the condition , leaving an effective parametrisation of the space of all such connections of with a residual gauge group action.
