Canonically ordered monoids

class ExistsMulOfLE (α : Type u) [Mul α] [LE α] : Prop

An OrderedCommMonoid with one-sided 'division' in the sense that if a ≤ b, there is some c for which a * c = b. This is a weaker version of the condition on canonical orderings defined by CanonicallyOrderedCommMonoid.

• exists_mul_of_le : ∀ {a b : α}, a ≤ b → ∃ (c : α), b = a * c

  For a ≤ b, a left divides b

class ExistsAddOfLE (α : Type u) [Add α] [LE α] : Prop

An OrderedAddCommMonoid with one-sided 'subtraction' in the sense that if a ≤ b, then there is some c for which a + c = b. This is a weaker version of the condition on canonical orderings defined by CanonicallyOrderedAddCommMonoid.

• exists_add_of_le : ∀ {a b : α}, a ≤ b → ∃ (c : α), b = a + c

  For a ≤ b, there is a c so b = a + c.

class CanonicallyOrderedAddCommMonoid (α : Type u_1) extends OrderedAddCommMonoid , OrderBot : Type u_1

A canonically ordered additive monoid is an ordered commutative additive monoid in which the ordering coincides with the subtractibility relation, which is to say, a ≤ b iff there exists c with b = a + c. This is satisfied by the natural numbers, for example, but not the integers or other nontrivial OrderedAddCommGroups.

class CanonicallyOrderedCommMonoid (α : Type u_1) extends OrderedCommMonoid , OrderBot : Type u_1

A canonically ordered monoid is an ordered commutative monoid in which the ordering coincides with the divisibility relation, which is to say, a ≤ b iff there exists c with b = a * c. Examples seem rare; it seems more likely that the OrderDual of a naturally-occurring lattice satisfies this than the lattice itself (for example, dual of the lattice of ideals of a PID or Dedekind domain satisfy this; collections of all things ≤ 1 seem to be more natural that collections of all things ≥ 1).
