Determinantal ideals of secant varieties
Daniele Agostini, Jinhyung Park
Using Hilbert schemes of points, we establish a number of results for a smooth projective variety in a sufficiently ample embedding. If is a curve or a surface, we show tha…

Coble duality for Jacobian Kummer fourfolds
Daniele Agostini, Pietro Beri, Franco Giovenzana +1
We study projective models of generalized Kummer fourfolds via O'Grady's theta groups and the classical Coble cubic. More precisely, we establish a duality between two singular mod…
