Krullring
A Krullring (after Wolfgang Krull ) is an integrity domain with the following property:
There is a set whose elements are discrete evaluation rings of the quotient field such that the following two conditions are met:
- For each out , there are only a finite number of evaluation rings , whose respective maximum ideal is contained. (Evaluation rings are local rings , i.e. they each have only one maximum ideal)
The first condition means: the average of the rating rings is off .
