Equi-affine minimal-degree moving frames for polynomial curves
Hoon Hong, Irina A. Kogan
We develop a theory and an algorithm for constructing minimal-degree polynomial moving frames for polynomial curves in an affine space. The algorithm is equivariant under volume-pr…

Almost Bijective Parametrization of Copositive Univariate Polynomials
Hoon Hong, Ezra Nance
In this work we develop a novel recursive method for parametrizing the cone of copositive univariate polynomials of any arbitrary degree . This parametrization is surjective, al…

Almost Bijective Parametrization of Copositive Matrices
Hoon Hong, Ezra Nance
In this work we take a deep dive into the cone of copositive matrices. In doing so we visualize the cone, make geometric observations about it, and prove them. We then…
