[Non réalité et non connectivité des polynômes complexes]
Pour les polynômes de deux variables complexes, nous construisons des contre-exemples aux questions suivantes : à équivalence topologique près, peut-on toujours trouver une équation réelle à un polynôme complexe (Lee Rudolph) ? Deux polynômes topologiquement équivalents peuvent-ils être reliés par une famille de polynômes topologiquement équivalents ?
Using the same method we provide negative answers to the following questions: is it possible to find real equations for complex polynomials in two variables up to topological equivalence (Lee Rudolph)? Can two topologically equivalent polynomials be connected by a continuous family of topologically equivalent polynomials?
