Abstract:
Let f : \C^2 \to \C be a mixed polynomial, i.e., a complex polynomial of variables (u, \bar{u}, v, \bar{v}) such that f(0) = 0 and that f has an isolated singularity at the origin. Then, associated with f, we have the well-defined link, which is the intersection of the mixed hypersurface $f^{-1}(0)$ with a sphere of small radius. Such a link is called a real algebraic link. Classification and characterization of algebraic links are still open. In this talk, a new construction of families of algebraic links is discussed and how properties of mixed polynomials are used to generate such families is explained.
