Construction of Symmetric Cubic Surfaces
Michela Brundu, Alessandro Logar, Federico Polli
We consider the action of the group on the smooth cubic surfaces of ( an algebraically closed field of characteristic zero). We classify, in…
On the slope inequalities for extremal curves
Valentina Beorchia, Michela Brundu
The present paper concerns the question of the violation of the r-th inequality for extremal curves in the projective r-space, posed by T. Kato and G. Martens. We show that the ans…
Multicones, duality and invariance for families of matrices
Michela Brundu, Marino Zennaro
In this paper we analyze the geometric structure and properties of a certain class of subsets of , known in the literature as 1-multicones, and here simply called multico…
On the singularities of surfaces ruled by conics
Michela Brundu, Gianni Sacchiero
We classify the singularities of a surface ruled by conics: they are rational double points of type or . This is proved by showing that they arise from a precise series…
Stratification of the moduli space of four--gonal curves
Michela Brundu, Gianni Sacchiero
Let be a smooth irreducible projective curve of genus and gonality 4. We show that the canonical model of is contained in a uniquely defined surface, ruled by conics, w…
