FINITE TYPE CONDITIONS ON REAL HYPERSURFACES WITH ONE DEGENERATE EIGENVALUE
【摘要】 Let M be a smooth pseudoconvex hypersurface in Cn+1 whose Levi form has at most one degenerate eigenvalue. For any tangent vector field L of type(1, 0), we prove the equality of the commutator type and the Levi form type associated to L. We also show that the regular contact type, the commutator type and the Levi form type of the real hypersurface are the same.
