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

Synopsis

• Function: divisorPoset

• Usage:

  P = divisorPoset(m, n)

• Inputs:
  • m, a ring element, the lower bound, which divides $n$
  • n, a ring element, the upper bound, which is a multiple of $m$
• Outputs:
  • P, an instance of the type Poset,
