Use, Smithsonian Three formulations of the classical theory and three approaches to quantization are discussed in some detail, and a number of other approaches are summarized. The generalization in the first lecture involves considering intersection theory on the moduli space of pairs consisting of a Riemann surface Σ and a holomorphic map of Σ to a fixed Kähler manifold K.
