A simple limit for slope instability
J. Stoppa, E. Tenni
Ross and Thomas have shown that subschemes can K-destabilise polarised varieties, yielding a notion known as slope (in)stability for varieties. Here we describe a special situation…
Divisors in the moduli spaces of curves
Enrico Arbarello, Maurizio Cornalba
In this mostly expository paper we review several known results about the cohomology of moduli spaces of smooth and stable curves, focusing in particular on low degree cohomology.…
On the finiteness theorem for rational maps on a variety of general type
Lucio Guerra, Gian Pietro Pirola
The dominant rational maps of finite degree from a fixed variety to varieties of general type, up to birational isomorphisms, form a finite set. This has been known as the Iitaka-S…
Siegel metric and curvature of the moduli space of curves
Elisabetta Colombo, Paola Frediani
We study the curvature of the moduli space M_g of curves of genus g with the Siegel metric induced by the period map. We give an explicit formula for the holomorphic sectional curv…
A conic bundle degenerating on the Kummer surface
Michele Bolognesi
Let be a genus 2 curve and $\su$ the moduli space of semi-stable rank 2 vector bundles on with trivial determinant. In \cite{bol:wed} we described the parameter space of no…
Infinitesimal invariant and vector bundles
Gian Pietro Pirola, Cecilia Rizzi
We study the Saito-Ikeda infinitesimal invariant of the ccle defined by curves in their jacobians using rank (k+1) vector bundles and we give a criterion for which the higher cycle…
