WebThen () is a rank one reflexive sheaf, and since () is defined as a subsheaf of , it is a fractional ideal sheaf (see below). Conversely, every rank one reflexive sheaf corresponds to a Weil divisor: The sheaf can be restricted to the regular locus, where it becomes free and so corresponds to a Cartier divisor (again, see below), and because ... Webis not the same as a locally free subsheaf of On X. For the correct notion of a sub vector bundle, convince yourself of the following. Let E be a locally free sheaf and F ˆE a subsheaf.
