Definition for commutative rings
For commutative rings, the notion of cancellative ring coincides with the notion of integral domain.
Definition for noncommutative rings
For noncommutative rings, there are three versions:
- Left-cancellative ring where the term on the left can be cancelled from any product
- Right-cancellative ring where the term on the right can be cancelled from any product
- Cancellative ring which is both left-cancellative and right-cancellative
