Some special systems of polynomial equations (anti-Vandermonde systems) and the definition fields of their solutions are studied. In the case of four variables it is proved that a definition field is an extension of a real quadratic field of degree 12.
Keywords: algebraic fields, Galois theory
Mots-clés : polynomial algebra.
