Category:Algebraic Closure

This category contains results about Algebraic Closure.
Definitions specific to this category can be found in Definitions/Algebraic Closure.

Let $\struct {S, \circ}$ be an algebraic structure.

Then $S$ has the property of closure under $\circ$ if and only if:

$\forall \tuple {x, y} \in S \times S: x \circ y \in S$

$S$ is said to be closed under $\circ$, or just that $\struct {S, \circ}$ is closed.
