Iterative polynomial regularisation of PIV-type: Hamiltonian systems and Newton polygons

Mathematical Physics 2025-10-16 v2 math.MP Exactly Solvable and Integrable Systems

Abstract

We study several polynomial Hamiltonian systems of PIV-type (including the mixed case quasi-PIV), and show that via the iterative process of polynomial regularisation, it is possible to identify the "minimal" Hamiltonian system. The selected Hamiltonian function is associated with the Newton polygon with minimal area and smallest highest total degree.
