Abstract

Semiholomorphic polynomials are functions f:C2Cf:\mathbb{C}^2\to\mathbb{C} that can be written as polynomials in complex variables uu, vv and the complex conjugate v\overline{v}. We prove the semiholomorphic analogoue of Akbulut's and King's "All knots are algebraic", that is, every link type in the 3-sphere arises as the link of a weakly isolated singularity of a semiholomorphic polynomial. Our proof is constructive, which allows us to obtain an upper bound on the polynomial degree of the constructed functions.
