# nil and nilpotent ideals

A ring $R$ is *nil* if every element in $R$ is nilpotent. Similarly, a one- or two-sided ideal is called *nil* if each of its elements is nilpotent.

A ring $R$ [resp. a one- or two sided ideal $A$] is *nilpotent* if $R^{n}=0$ [resp. $A^{n}=0$] for some positive integer $n$.

A ring or an ideal is *locally nilpotent* if every finitely generated subring is nilpotent.

The following implications hold for rings (or ideals):

$\text{nilpotent}\quad\Rightarrow\text{locally nilpotent}\quad\Rightarrow\text{nil}$ |
