Category:Irreducible Elements of Rings
This category contains results about Irreducible Elements of Rings.
Definitions specific to this category can be found in Definitions/Irreducible Elements of Rings.
Let $\struct {D, +, \circ}$ be an integral domain whose zero is $0_D$.
Let $\struct {U_D, \circ}$ be the group of units of $\struct {D, +, \circ}$.
Let $x \in D: x \notin U_D, x \ne 0_D$, that is, $x$ is non-zero and not a unit.
Definition 1
$x$ is defined as irreducible if and only if it has no non-trivial factorization in $D$.
That is, if and only if $x$ cannot be written as a product of two non-units.
Definition 2
$x$ is defined as irreducible if and only if the only divisors of $x$ are its associates and the units of $D$.
That is, if and only if $x$ has no proper divisors.
