A characterization of Cayley Hypersurface and Eastwood and Ezhov conjecture
Eastwood and Ezhov generalized the Cayley surface to the Cayley hypersurface in each dimension, proved some characteristic properties of the Cayley hypersurface and conjectured that a homogeneous hypersurface in affine space satisfying these properties must be the Cayley hypersurface. We will prove this conjecture when the domain bounded by a graph of a function defined on Rn is also homogeneou...
متن کاملA ug 2 00 4 TOWARDS A CLASSIFICATION OF HOMOGENEOUS TUBE DOMAINS IN C 4
We classify the tube domains in C 4 with affinely homogeneous base whose boundary contains a non-degenerate affinely homogeneous hypersurface. It follows that these domains are holo-morphically homogeneous and amongst them there are four new examples of unbounded homogeneous domains (that do not have bounded realisations). These domains lie to either side of a pair of Levi-indefinite hypersurfa...
متن کاملCayley Hypersurfaces
This is the Cayley surface when N = 3. The next few are as follows. x4 = x1x3 + 1 2 x2 2 − x1 x2 + 1 4 x1 4 x5 = x1x4 + x2x3 − x1 x3 − x1x2 2 + x1 x2 − 1 5 x1 5 x6 = x1x5 + x2x4 + 1 2 x3 2 − x1 x4 − 2x1x2x3 − 1 3 x2 3 + x1 x3 + 3 2 x1 x2 2 − x1 x2 + 1 6 x1 . Since the first term in (1) is −xN and this is the only occurrence of this variable, these hypersurfaces are polynomial graphs over the re...
متن کاملElliptic Cr-manifolds and Shear Invariant Ode with Additional Symmetries
We classify the ODEs that correspond to elliptic CR-manifolds with maximal isotropy. It follows that the dimension of the isotropy group of an elliptic CR-manifold can be only 10 (for the quadric), 4 (for the listed examples) or less. This is in contrast with the situation of hyperbolic CR-manifolds, where the dimension can be 10 (for the quadric), 6 or 5 (for semi-quadrics) or less than 4. We ...
متن کاملOn Chern-Moser Normal Forms of Strongly Pseudoconvex Hypersurfaces with High-Dimensional Stability Group
We explicitly describe germs of strongly pseudoconvex non-spherical real-analytic hypersurfaces M at the origin in Cn+1 for which the group of local CR-automorphisms preserving the origin has dimension d0(M) equal to either n 2 − 2n + 1 with n ≥ 2, or n2 − 2n with n ≥ 3. The description is given in terms of equations defining hypersurfaces near the origin, written in the Chern-Moser normal form...
