Strictly positive polynomials in the boundary of the SOS cone

Santiago Laplagne, Marcelo Valdettaro

We study the boundary of the cone of real polynomials that can be decomposed as a sum of squares (SOS) of real polynomials. This cone is included in the cone of nonnegative polynom…

Subresultants of and , Jacobi polynomials and complexity

A. Bostan, T. Krick, A. Szanto +1

In an earlier article together with Carlos D'Andrea [BDKSV2017], we described explicit expressions for the coefficients of the order- polynomial subresultant of and $(…

Closed formula for univariate subresultants in multiple roots

Carlos D'Andrea, Teresa Krick, Agnes Szanto +1

We generalize Sylvester single sums to multisets (sets with repeated elements), and show that these sums compute subresultants of two univariate polyomials as a function of their r…

Subresultants in multiple roots: an extremal case

Alin Bostan, Carlos D'Andrea, Teresa Krick +2

We provide explicit formulae for the coefficients of the order-d polynomial subresultant of (x-α)^m and (x-β)^n with respect to the set of Bernstein polynomials \{(x-α)^j(x-β)^{d-j…

Symmetric Interpolation, Exchange Lemma and Sylvester Sums

Teresa Krick, Agnes Szanto, Marcelo Valdettaro

The theory of symmetric multivariate Lagrange interpolation is a beautiful but rather unknown tool that has many applications. Here we derive from it an Exchange Lemma that allows…
