On linear systems of with nine base points
Maria Chiara Brambilla, Olivia Dumitrescu, Elisa Postinghel
We study special linear systems of surfaces of interpolating nine points in general position having a quadric as fixed component. By performing degenerations in the…

Faithful tropicalisation and torus actions
Jan Draisma, Elisa Postinghel
For any affine variety equipped with coordinates, there is a surjective, continuous map from its Berkovich space to its tropicalisation. Exploiting torus actions, we develop techni…

Vanishing theorems for linearly obstructed divisors
Olivia Dumitrescu, Elisa Postinghel
We study divisors in the blow-up of at points in general position that are non-special with respect to the notion of linear speciality introduced in [5]. We describe…
