A Novel Necessary and Sufficient Condition for the Positivity of a Binary Quartic Form
In this paper, by considering the common points of two conics instead of the roots of the binary quartic form, we propose a novel necessary and sufficient condition for the positivity of a binary quartic form using the theory of the pencil of conics. First, we show the degenerate members of the penc...
