I shall survey recent wellposedness results for the Cauchy problem of NLS on compact surfaces, with some emphasis on the role played by the geometry of the surface. The case of the sphere, where a new instability phenomenon occurs, will be discussed in detail, in connection with bilinear estimates on spherical harmonics.
