behavior
If is an infinite cyclic ring (http://planetmath.org/CyclicRing3), the behavior of is a nonnegative integer such that there exists a generator (http://planetmath.org/Generator) of the additive group
of with .
If is a finite cyclic ring of order , the behavior of is a positive divisor of such that there exists a generator of the additive group of with .
For any cyclic ring, behavior exists uniquely. Moreover, the behavior of a cyclic ring determines many of its .
To the best of my knowledge, this definition first appeared in my master’s thesis:
