Positive divisors on quotients of and the Mori cone of
Claudio Fontanari
We prove that if then every -invariant F-nef divisor on the moduli space of stable -pointed curves of genus zero is linearly equivalent to an effective combinat…
A perfect stratification of M_g for g at most 5
Claudio Fontanari, Eduard Looijenga
We find for g at most 5 a stratification of depth g-2 of the moduli space of curves M_g with the property that its strata are affine and the classes of their closures provide a Q-b…
On the birational geometry of moduli spaces of pointed curves
Edoardo Ballico, Gianfranco Casnati, Claudio Fontanari
We prove that the moduli space ${\Cal M}_{g,n}$ of smooth curves of genus with marked points is rational for and , and it is unirational for and…
Quantum cohomology of moduli spaces of genus zero stable curves
Claudio Fontanari
We investigate the (small) quantum cohomology ring of the moduli spaces of stable n-pointed curves of genus 0. In particular, we determine an explicit presentation in the case n=5…
