2012 (English)In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 109, no 15, 5600-5602 p.Article in journal (Refereed) Published
In this note we discuss an analog of the classical Waring problem for C[x(0),x(1),..., x(n)]- Namely, we show that a general homogeneous polynomial p is an element of C[x(0),x(1),..,x(n)] of degree divisible by k >= 2 can be represented as a sum of at most k(n) k-th powers of homogeneous polynomials in C[x(0),x(1),...,x(n)]. Noticeably, k(n) coincides with the number obtained by naive dimension count.
