Rational cuspidal curves with four cusps on Hirzebruch surfaces
arXiv:1303.4178
Abstract
The purpose of this article is to shed light on the question of how many and what kind of cusps a rational cuspidal curve on a Hirzebruch surface can have. We use birational transformations to construct rational cuspidal curves with four cusps on the Hirzebruch surfaces and find associated results for these curves.
