#660 ⟨a, b | ab=aa, bb=aa⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 8
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ b = a2 and a ⋅ a = a2, however b ≠ a
- Not right cancellative, because right multiplication by a is not injective:
-
ba ⋅ a = a3 and a2 ⋅ a = a3, however ba ≠ a2
- Reduction order:
- Left-to-right shortlex with a < b
- Certificate: derivations of all rewriting rules from the defining relations.
# ab:ab=aa,bb=aa ab - -
ab=aa
bb=aa
baa=aaa
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
