Sheaf of algebras
http://ift.tt/eA8V8J
In algebraic geometry, a sheaf of algebras on a ringed space X is a sheaf of commutative rings on X that is also a sheaf of O X {\displaystyle {\mathcal {O}}_{X}} {\mathcal {O}}_{X} -modules. It is quasi-coherent if it is so as a module. When X is a scheme, just like a ring, one can take the global Spec of a ...
