Lagrangian fibration structure on the cotangent bundle of a del Pezzo surface of degree 4
Let [Formula: see text] be a del Pezzo surface of degree 4, and let [Formula: see text] be the cotangent bundle of [Formula: see text]. In this paper, we show that there is a natural map [Formula: see text] admitting Lagrangian fibration structure. Moreover, we explicitly describe all fibers of [Formula: see text].
