WebMore algebraically, we can tank about a rank-nlocally free O X-module. Xis a locally ringed space, O X is its sheaf of rings, and an O X-module is a sheaf which is a module over O X in a suitable sense. Another way to say locally free is projective. Given a vector bundle ˇ: E !X in the geometric sense, we can pass to the O WebUntitled - Free download as PDF File (.pdf), Text File (.txt) ...
