This paper is devoted to determine the geometry of a class of smooth projective rational surfaces whose minimal models are the Hirzebruch ones; concretely, they are obtained as the blowup of a Hirzebruch surface at collinear points. Explicit descript

The aim of this work was to study the finite generation of the effective monoid and Cox ring of a Platonic Harbourne-Hirschowitz rational surface with an anticanonical divisor not reduced which contains some exceptional curves as irreducible componen

In this paper, we provide new families of smooth projective rational surfaces whose Cox rings are finitely generated. These surfaces are constructed by blowing-up points in Hirzebruch surfaces and may have very high Picard numbers. Such construction

The aim of this paper is to give a geometric characterization of the finite generation of the Cox rings of anticanonical rational surfaces. This characterization is encoded in the finite generation of the effective monoid. Furthermore, we prove that

We add a reasonable hypothesis in Theorem 1 in Rev. Mat. Iberoam. 31 (2015) no. 4, 1131–1140, in order to make it correct.
