#2995 ⟨a, b, c | aab=c, cab=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 ⋅ (ab)2 = a2b and a ⋅ ab = a2b, however (ab)2 ≠ ab
- Not right cancellative, because right multiplication by b is not injective:
-
a2ba ⋅ b = a2b and a2 ⋅ b = a2b, however a2ba ≠ a2
- 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:aab=c,cab=c ab/c - -
aabab=aab
c=aab
The mapping is from the listed presentation's alphabet to the current rewriting system's alphabet.
