Abstract

V originále

We give a classification of Sasakian manifolds that are CR-equivalent to hyperquadrics by describing their exact parameter space. For " half" of the parameter space, we find an explicit representation by defining equations. This problem is related to the problem of finding pseudo-Kahler potentials with prescribed Ricci curvature.
