Blown-up toric surfaces with non-polyhedral effective cone
Ana-Maria Castravet, Antonio Laface, Jenia Tevelev +1
We construct examples of projective toric surfaces whose blow-up at a general point has a non-polyhedral pseudo-effective cone, both in characteristic and in every prime charac…
Chilean configuration of conics, lines and points
Igor Dolgachev, Antonio Laface, Ulf Persson +1
Using the theory of rational elliptic fibrations, we construct and discuss a one parameter family of configurations of conics and points in the projective plane that reali…
On secant defectiveness and identifiability of Segre-Veronese varieties
Antonio Laface, Alex Massarenti, Rick Rischter
We give an almost asymptotically sharp bound for the non secant defectiveness and identifiability of Segre-Veronese varieties. We also provide new examples of defective Segre-Veron…
