Abstract |
|
In this paper, we note that the incidence cycles of a seminormal curve X intervene in the calculation of the arithmetic genus pa(X), of the algebraic fundamental group π1alg(X) and of the Picard group Pic(X) of X. Really we do not consider only seminormal curves, but more generally varieties obtained from a smooth variety by glueing a finite set of points. |
