## Counting surfaces singular along a line in $\PP^3$
 We enumerate the number of surfaces of degree $d$ in $\PP^3$ having a singular line of order $k$, passing through $\delta$ generic points (where $\delta$ is the dimension of moduli space of such surfaces. Our approach is a computation using Chern characters. Joint work with S. Carmieli.
