#5397 ⟨a, b | aab=ba, baa=bb⟩
Contents
- Properties
- Rewriting system
- Isomorphic instances
- Sum of relation sides is 10
- Infinite non-cancellative non-commutative monoid
- Element a has infinite order
- Not left cancellative, because left multiplication by a is not injective:
-
a ⋅ a7b = a6b and a ⋅ a5b = a6b, however a7b ≠ a5b
- Not right cancellative, because right multiplication by b is not injective:
-
b ⋅ b = a4b and a4 ⋅ b = a4b, however b ≠ a4
- Reduction order:
- Right-to-left recursive path with deg(a) = 0; deg(b) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
# ab:aab=ba,baa=bb reversed:a/b - -
aaaaaaaab=aaaaaab
ba=aab
bb=aaaab
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
