On a decomposition of polynomials in several variables
Journal de théorie des nombres de Bordeaux, Tome 14 (2002) no. 2, pp. 647-666.

On considère la représentation d'un polynôme a plusieurs variables comme une somme de polynômes à une variable en combinaisons linéaires des variables.

One considers representation of a polynomial in several variables as the sum of values of univariate polynomials taken at linear combinations of the variables.
