#5408 ⟨a, b | aab=bb, abb=aa⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 10
- Infinite non-cancellative non-commutative monoid
- Element ab has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ a4 = a2 and a ⋅ a = a2, however a4 ≠ a
- Not right cancellative, because right multiplication by a is not injective:
-
a4 ⋅ a = a2 and a ⋅ a = a2, however a4 ≠ a
- Reduction order:
- Left-to-right recursive path with deg(a) = 0; deg(b) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
# ab:aab=bb,abb=aa a/b - -
aaaaa=aa
baa=aaaa
aab=aaaa
bb=aaaa
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
