#5691 ⟨a, b, c | aa=b, abc=bc⟩
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 ⋅ a2c = a2c and a ⋅ ac = a2c, however a2c ≠ ac
- Not right cancellative, because right multiplication by c is not injective:
-
a3 ⋅ c = a2c and a2 ⋅ c = a2c, however a3 ≠ a2
- Reduction order:
- Left-to-right recursive path with deg(a) = deg(c) = 0, a < c; deg(b) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
# abc:aa=b,abc=bc ac/b - -
aaac=aac
b=aa
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
