Terrà  un seminario dal titolo:

“Multivariate polynomials as sums of univariate polynomials in linear forms.”

Abstract

Let d,n be positive integers and K a field of characteristic 0 or >d.

If |K| > 2d-3,then every polynomial f in K[x_1,...,x_n] of degree d is a sum of at most (d + n -2|d-1) terms f_m(l_m) with f_m in K[z] and l_m in K[x_1,...,x_n] a linear form(Colloq.Math 112,2008,201-233).Several open problems are discussed.

Tutti gli interessati sono invitati a partecipare.
