Sylvester关于次结式的双重和的初等证明

An Elementary Proof of Sylvester's Double Sums for Subresultants

Carlos D'Andrea, Hoon Hong, Teresa Krick, Agnes Szanto

摘要:

在1853年西尔维斯特指出,并证明了一个优雅的公式,表示多项式subresultants在根的输入多项式。Sylvester公式最近也被Lascoux和Pragacz用多Schur函数和除差证明。在本文中,我们提供了一个初等的证明,只使用矩阵乘法和范德蒙行列式的基本性质。

英文摘要:

In 1853 Sylvester stated and proved an elegant formula that expresses the polynomial subresultants in terms of the roots of the input polynomials. Sylvester's formula was also recently proved by Lascoux and Pragacz by using multi-Schur functions and divided differences. In this paper, we provide an elementary proof that uses only basic properties of matrix multiplication and Vandermonde determinants.
