The Fulton-MacPherson compactification is not a Mori dream space

Patricio Gallardo, José Luis González, Evangelos Routis

We show that the Fulton-MacPherson compactification of the configuration space of distinct labeled points in certain varieties of arbitrary dimension , including projective…

The geography of negative curves

Javier González-Anaya, José Luis González, Kalle Karu

We study the Mori Dream Space (MDS) property for blowups of weighted projective planes at a general point and, more generally, blowups of toric surfaces defined by a rational plane…

Curves generating extremal rays in blowups of weighted projective planes

Javier González-Anaya, José Luis González, Kalle Karu

We consider blowups at a general point of weighted projective planes and, more generally, of toric surfaces with Picard number one. We give a unifying construction of negative curv…

Generation of jets and Fujita's jet ampleness conjecture on toric varieties

José Luis González, Zhixian Zhu

Jet ampleness of line bundles generalizes very ampleness by requiring the existence of enough global sections to separate not just points and tangent vectors, but also their higher…

Constructing non-Mori Dream Spaces from negative curves

Javier González-Anaya, José Luis González, Kalle Karu

We study blowups of weighted projective planes at a general point, and more generally blowups of toric surfaces of Picard number one. Based on the positive characteristic methods o…

On a family of negative curves

Javier González-Anaya, José Luis González, Kalle Karu

Let be the blowup of a weighted projective plane at a general point. We study the problem of finite generation of the Cox ring of . Generalizing examples of Srinivasan and K…
