The Sylvester-Chvatal Theorem

The Sylvester-Gallai theorem asserts that every finite set S of points in two-dimensional Euclidean space includes two points, a and b, such that either there is no other point in S is on the line ab, or the line ab contains all the points in S. V. Chvátal extended the notion of lines to arbitrary metric spaces and made a conjecture that generalizes the Sylvester-Gallai theorem. In the present ...

Sylvester versus Gundelfinger

Let Vn be the SL2-module of binary forms of degree n and let V = V1 ⊕ V3 ⊕ V4. We show that the minimum number of generators of the algebra R = C[V ]2 of polynomial functions on V invariant under the action of SL2 equals 63. This settles a 142-year old question.

Rectangular Corner Cutting Sylvester

This paper presents a way to construct the Sylvester A-resultant matrix for three bi-degree (m; n) polynomials whose exponent set is cut oo by rectangles at the corners. The paper also shows that the determinant of this matrix does give the resultant of the three polynomials.
