%0 Journal Article %T Hopf Hypersurfaces of Small Hopf Principal Curvature in CH^2 %A Thomas A. Ivey %A Patrick J. Ryan %J Mathematics %D 2008 %I arXiv %X Using the methods of moving frames and exterior differential systems, we show that there exist Hopf hypersurfaces in complex hyperbolic space CH^2 with any specified value of the Hopf principal curvature less than or equal to the corresponding value for the horosphere. We give a construction for all such hypersurfaces in terms of Weierstrass-type data, and also obtain a classification of pseudo-Einstein hypersurfaces in CH^2. %U http://arxiv.org/abs/0812.4535v1
