Abstract:In this paper, we study the collection of all real-analytic hypersurfaces in C 2 of the form M = (z, w) : Im w = Re w θ(|z| 2 ) . We compute all local automorphisms for such hypersurfaces, providing new examples of hypersurfaces with stability groups determined by arbitrary jet-orders. Moreover, we show that for such hypersurfaces, if the stability group is not determined by 1-jets, then the hypersurface is "generically" spherical. That is, such hypersurfaces are locally spherical at every point except those a… Show more
