On positive bivariate quartic forms

Algebraic Geometry 2015-07-28 v1

Abstract

A bivariate quartic form is a homogeneous bivariate polynomial of degree four. A criterion of positivity for such a form is known. In the present paper this criterion is reformulated in terms of pseudotensorial invariants of the form.
