Combinatorial aspects of nodal curves
Simone Busonero, Margarida Melo, Lidia Stoppino
To any nodal curve is associated the degree class group, a combinatorial invariant which plays an important role in the compactification of the generalised Jacobian of and…

A sharp bound for the slope of double cover fibrations
M. Cornalba, L. Stoppino
Let f: X->B be a fibred surface of genus g whose general fibre is a double cover of a smooth curve of genus gamma. We show that, for g > 4gamma+1, the number 4(g-1)/(g-gamma) is a…

Slope inequalities for fibred surfaces via GIT
Lidia Stoppino
In this paper we present a generalisation of a theorem due to Cornalba and Harris, which is an application of Geometric Invariant Theory to the study of invariants of fibrations. I…
