Representations of multivariate polynomials by sums of univariate polynomials in linear forms

A. Białynicki-Birula, A. Schinzel (2008)

Colloquium Mathematicae

Similarity:

The paper is concentrated on two issues: presentation of a multivariate polynomial over a field K, not necessarily algebraically closed, as a sum of univariate polynomials in linear forms defined over K, and presentation of a form, in particular a zero form, as the sum of powers of linear forms projectively distinct defined over an algebraically closed field. An upper bound on the number of summands in presentations of all (not only generic) polynomials and forms of a given number of...

On a decomposition of polynomials in several variables

Andrzej Schinzel (2002)

Journal de théorie des nombres de Bordeaux

Similarity:

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