Chern Classes of the Moduli Stack of Curves
Gilberto Bini
Here we calculate the Chern classes of , the moduli stack of stable n-pointed curves. In particular, we prove that such classes lie in the tautological r…
Euler Characteristics of Moduli Spaces of Curves
Gilberto Bini, John Harer
Let be the moduli space of n-pointed Riemann surfaces of genus g. Denote by the Deligne-Mumford compactification of . I…
Moduli of Curves and Spin Structures via Algebraic Geometry
Gilberto Bini, Claudio Fontanari
Here we investigate some birational properties of two collections of moduli spaces, namely moduli spaces of (pointed) stable curves and of (pointed) spin curves. In particular, we…
On the work of Givental relative to mirror symmetry
G. Bini, C. De Concini, M. Polito +1
These are the informal notes of two seminars held at the Universita` di Roma "La Sapienza", and at the Scuola Normale Superiore in Pisa in Spring and Autumn 1997. We discuss in det…
A formula for the Euler characteristic of
G. Bini, G. Gaiffi, M. Polito
In this paper we compute the generating function for the Euler characteristic of the Deligne-Mumford compactification of the moduli space of smooth n-pointed genus 2 curves.
