Completely Reducible Ternary Cubic Forms

Commutative Algebra 2021-07-07 v1

Abstract

We discuss various necessary and sufficient conditions for the complete reducibility of a ternary cubic form. In doing so, we prove the claim made in the 19th century that such a form is completely reducible if and only if its Hessian is a multiple of itself.
