Descending the ground field in sums of squares representations
| Type of Publication: | Preprint |
| Author: | Scheiderer, Claus |
| Year of publication: | 2012 |
| ArXiv-ID: | arXiv:1209.2976 |
| Summary: |
We construct explict polynomials with rational coefficients which are sums of squares of polynomials with real coefficients, but not of polynomials with rational coefficients. Whether or not such examples exist was an open question originally raised by Sturmfels.
