Arithmetical ring

For all ideals ${\displaystyle {\mathfrak {a}},{\mathfrak {b}}}$, and ${\displaystyle {\mathfrak {c}}}$,

${\displaystyle {\mathfrak {a}}\cap ({\mathfrak {b}}+{\mathfrak {c}})=({\mathfrak {a}}\cap {\mathfrak {b}})+({\mathfrak {a}}\cap {\mathfrak {c}})}$

For all ideals ${\displaystyle {\mathfrak {a}},{\mathfrak {b}}}$, and ${\displaystyle {\mathfrak {c}}}$,

${\displaystyle {\mathfrak {a}}+({\mathfrak {b}}\cap {\mathfrak {c}})=({\mathfrak {a}}+{\mathfrak {b}})\cap ({\mathfrak {a}}+{\mathfrak {c}})}$

The last two conditions both say that the lattice of all ideals of Risdistributive.

An arithmetical domain is the same thing as a Prüfer domain.
