#3046 ⟨a, b, c | aba=c, abc=c⟩
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 ⋅ (ba)2 = aba and a ⋅ ba = aba, however (ba)2 ≠ ba
- Not right cancellative, because right multiplication by a is not injective:
-
(ab)2 ⋅ a = aba and ab ⋅ a = aba, however (ab)2 ≠ ab
- Reduction order:
- Left-to-right recursive path with deg(a) = deg(b) = 0, a < b; deg(c) = 1
- Certificate: derivations of all rewriting rules from the defining relations.
# abc:aba=c,abc=c ab/c - -
ababa=aba
c=aba
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
