Classification of Okamoto-Painlevé Pairs
arXiv:math/0006028
Abstract
In this paper, we introduce the notion of an Okamoto-Painlevé pair (S, Y) which consists of a compact smooth complex surface S and an effective divisor Y on S satisfying certain conditions. Though spaces of initial values of Painlevé equations introduced by K. Okamoto give examples of Okamoto-Painleve pairs, we find a new example of Okamoto-Painlevé pairs not listed in \cite{Oka}. We will give the complete classification of Okamoto-Painlevé pairs.
