A matrix-based approach to properness and inversion problems for rational surfaces

Carlos D'Andrea, Laurent Buse

We present a matrix-based algorithm for deciding if the parametrization of a curve or a surface is invertible or not, and for computing the inverse of the parametrization if it exi…

The Cayley-Menger determinant is irreducible for $n \geq 3$

Carlos D'Andrea, Martin Sombra

We prove that the Cayley-Menger determinant of an $n$ -dimensional simplex is an absolutely irreducible polynomial for $n \geq 3.$ We also study the irreducibility of polynomials asso…

On the irreducibility of the determinant of the matrix of moving planes

Carlos D'Andrea

We show that, for generic bihomogeneous polynomials, the determinant of the matrix of moving planes is irreducible.

Implicitization of rational surfaces using toric varieties

Amit Khetan, Carlos D'Andrea

A parameterized surface can be represented as a projection from a certain toric surface. This generalizes the classical homogeneous and bihomogeneous parameterizations. We extend t…
