| Research Abstract |
The following three results are obtained about the boundary description on the moduli of normal isolated complex singularities :
(1) Descriptions of the first order deformations of rational surface singularities A_<n,q> are obtained using the invariant spherical harmonic forms.
(2) The versal deformation of resolution of normal isolated singularities is complex analytically constructed.
(3) A framework of constructing the versal deformation of CR structures with fixing a contact structures on a boundary of normal isolated singularities of complex dimension three or higher is established under the equivalence of CR structures connected by the Hamiltonian flows.
