The Chow Ring of the Stack of Rational Curves with at most 3 Nodes
Damiano Fulghesu
In this paper we explicit the rational Chow ring of the stack consisting of nodal curves of genus 0 with at most 3 nodes: it is a Q-algebra with 10 generators and 11 relations.
Tautological Classes of the Stack of Rational Nodal Curves
Damiano Fulghesu
This is the second in a series of three papers in which we investigate the rational Chow ring of the stack consisting of nodal curves of genus. Here we define the basic classes: th…
The Stack of Rational Nodal Curves
Damiano Fulghesu
In this series of three papers we start to investigate the rational Chow ring of the stack consisting of nodal curves of genus 0, in particular we determine completely the rational…
The integral Chow ring of the stack of hyperelliptic curves of even genus
Dan Edidin, Damiano Fulghesu
Let be an even positive integer. In this paper we compute the integral Chow ring of the stack of smooth hyperelliptic curves of genus .
On the Chow ring of the stack of rational nodal curves
Damiano Fulghesu
The goal of this paper is to compute the rational Chow ring of the stack consisting of nodal curves of genus 0 with at most 3 nodes: it is a Q-algebra with 10 generators and 11 rel…
The integral Chow ring of the stack of at most 1-nodal rational curves
Dan Edidin, Damiano Fulghesu
We give a presentation for the stack of rational curves with at most 1 node as the quotient by GL(3) of an open set in a 6-dimensional irreducible representation. We then use equiv…
