The bifurcation set of a rational function via Newton polytopes
arXiv:2003.13308
Abstract
The bifurcation sets of polynomial functions have been studied by many mathematicians from various points of view. In particular, Némethi and Zaharia described them in terms of Newton polytopes. In this paper, we will show analogous results for rational functions.
