{wiki=Torsion_sheaf}
In algebraic geometry and the broader context of sheaf theory, a **torsion sheaf** is a type of sheaf that is closely related to the concept of torsion elements in algebraic structures. More formally, a torsion sheaf is defined in the context of a sheaf of abelian groups (or modules) associated with a topological space or a scheme. \#\#\# Definition 1.
