In algebra, particularly in the context of module theory, torsion refers to a property of elements in a module over a ring. More specifically, let \\( M \\) be a module over a ring \\( R \\). An element \\( m \\in M \\) is said to be a torsion element if there exists a non-zero element \\( r \\in R \\) such that \\( r \\cdot m = 0 \\).
