Posets :: divisorPoset(RingElement,RingElement)

divisorPoset(RingElement,RingElement) -- generates the poset of divisors with a lower and upper bound

Synopsis

Description

This method generates the divisor poset of $n$ with elements which are multiples of $n$.

i1 : R = QQ[x,y];
i2 : divisorPoset(x*y-x, x^2*y^2 - 2*x^2*y + x^2)

o2 = Relation Matrix: | 1 1 1 1 |
                      | 0 1 0 1 |
                      | 0 0 1 1 |
                      | 0 0 0 1 |
