Unclear naming[edit]

The article on Spectrum of a Ring, when it defines the sheaf structure on Spec(R) introduces a notation $\Gamma(U,O_X)$ without warning and never defines $\Gamma(_,_)$. It needs to be self-contained, regardless of how common or simple that usage is, it needs to be defined.Machinetomakecoffee (talk) 18:01, 21 April 2021 (UTC)[reply]
