sheaf

In mathematics, specifically in algebraic geometry and related areas, a sheaf is a tool for systematically tracking locally defined data attached to the open sets of a topological space. The data can be thought of as sections of a bundle over the space. The key property of sheaves is that they can "glue" data defined on overlapping open sets. More formally, a sheaf F over a topological space X is a contravariant functor from the category of open sets in X to the category of sets (or abelian groups, or modules, etc.) which satisfies the following conditions: 1. For every open cover {Ui} of an open set U in X, if s is a section over U, and s restricts to the same section over each intersection Ui ∩ Uj for all i, j, then s must restrict to the same section over each Ui. 2. For every open cover {Ui} of U, if a section si over each Ui restricts to the same section over each intersection Ui ∩ Uj for all i, j, then there is a unique section s over U that restricts to each si over Ui. These two properties are referred to as locality and gluing, respectively. Sheaves allow us to make precise the intuitive idea of defining geometric or algebraic objects locally, and then patching these local pieces together to obtain a global object.

### Wikidata

Sheaf

In mathematics, a sheaf is a tool for systematically tracking locally defined data attached to the open sets of a topological space. The data can be restricted to smaller open sets, and the data assigned to an open set is equivalent to all collections of compatible data assigned to collections of smaller open sets covering the original one. For example, such data can consist of the rings of continuous or smooth real-valued functions defined on each open set. Sheaves are by design quite general and abstract objects, and their correct definition is rather technical. They exist in several varieties such as sheaves of sets or sheaves of rings, depending on the type of data assigned to open sets. There are also maps from one sheaf to another; sheaves with their morphisms on a fixed topological space form a category. On the other hand, to each continuous map there is associated both a direct image functor, taking sheaves and their morphisms on the domain to sheaves and morphisms on the codomain, and an inverse image functor operating in the opposite direction. These functors, and certain variants of theirs, are essential parts of sheaf theory.
