#2826 ⟨a, b, c | aaa=b, aca=b⟩
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 ⋅ ca = a3 and a ⋅ a2 = a3, however ca ≠ a2
- Not right cancellative, because right multiplication by a is not injective:
-
ac ⋅ a = a3 and a2 ⋅ a = a3, however ac ≠ 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:aaa=b,aca=b ac/b - -
aca=aaa
b=aaa
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
