Characteristic numbers of rational cuspidal space curves
Dung Nguyen
We solve the problem of computing characteristic numbers of rational space curves with a cusp, where there may or may not be a condition on the node. The solution is given in the f…
Characteristic numbers of ellitpic space curves with fixed j-invariant
Dung Nguyen
We solve the problem of counting elliptic curves with fixed j-invariant in projective space with tangency conditions. This is equivalent to couting rational nodal curves with condi…
Characteristic numbers of elliptic space curves
Dung Nguyen
We solve the problem of characteristic numbers of elliptic curves in any dimensional projective space The answers are given in the form of effective recursions. Many numerical exam…
Characteristic numbers of rational nodal curves in
Dung Nguyen
In this paper we compute the number of rational curves with one node passing through a given number of points, lines and tangent to a given number of planes in .
