Rectangular corner cutting and Sylvester A-resultants
Ming Zhang, Ron Goldman · 2000
We present a way to construct the Sylvester A-resultant matrix for three bi-degree (m, n) polynomials whose Newton polygon is modified by cutting off rectangles at the corners. We also show that the determinant of this matrix is generically non-singular, so this determinant is indeed the resultant of the three original bivariate polynomials.
