Teichmuller space for a compact oriented surface M without boundary is described as the quotient ji/B0, where s?is the space of almost complex structures on M (compatible with a given orientation) and 8)0 are those C°° diffeomorphisms homotopic to the identity. There is a natural 3>0 invariant L2 Riemannian structure on si which induces a Riemannian structure on si/3>n. Infinitesimally this is the bilinear pairing suggested by Andre Weil—the Weil-Petersson Riemannian struc- ture. The structure is shown to be Kahler with respect to a naturally induced complex structure on?//S0.
