Non-existence of negative curves
Javier González-Anaya, José Luis González, Kalle Karu
Let be a projective toric surface of Picard number one blown up at a general point. We bring an infinite family of examples of such whose Kleiman-Mori cone of curves is not…
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…
