Outline of Final Research Achievements |
We clarrified the structure of Newton non-degenerate mixed singularities. In particular, we gave a formula for the zeta function of mixed function with strongly polar weighted face functions. We also showed the existence of the contact structure on such a link. We also showed the relation of the moduli space of strongly mixed homogeneous polynomials of two variables and the moduli of mixed polynomials of one variables and the range of possible number of roots.It is also shown that the Lens equation studied in astro-physics has strongly related to our moduli problem.
