Invertible sheaf. In mathematics, an invertible sheaf is a sheaf on a ringed space which has an inverse with respect to tensor product of sheaves of modules. It is the equivalent in algebraic geometry of the topological notion of a line bundle. Due to their interactions with Cartier divisors, they play a central role in the study of algebraic ...

Exponential sheaf sequence. In mathematics, the exponential sheaf sequence is a fundamental short exact sequence of sheaves used in complex geometry . Let M be a complex manifold, and write OM for the sheaf of holomorphic functions on M. Let OM * be the subsheaf consisting of the non-vanishing holomorphic functions.
Jun 6, 2020 · Quasi-coherent sheaf. A sheaf of modules locally defined by generators and relations. More precisely, let $ X $ be a topological space and let $ {\mathcal A} $ be a sheaf of rings on $ X $; a sheaf $ {\mathcal F} $ of $ {\mathcal A} $- modules is called quasi-coherent if for any point $ x \in X $ there is an open neighbourhood $ U $ and an ...
