Arithmetical ring

In algebra, a commutative ring R is said to be arithmetical (or arithmetic) if any of the following equivalent conditions holds: 1. * The localization of R at is a uniserial ring for every maximal ideal of R. 2. * For all ideals , and , 3. * For all ideals , and , The last two conditions both say that the lattice of all ideals of R is distributive. An arithmetical domain is the same thing as a Prüfer domain.
