Proof
1 Non-Joinable Fork
The system is not confluent due to the following forking derivations.
| t0
|
= |
0(0(1(0(x)))) |
|
→ε
|
0(2(0(0(3(1(x)))))) |
|
= |
t1
|
| t0
|
= |
0(0(1(0(x)))) |
|
→ε
|
0(2(0(4(1(0(x)))))) |
|
= |
t1
|
The two resulting terms cannot be joined for the following reason:
- When applying the cap-function on both terms (where variables may be treated like constants)
then the resulting terms do not unify.
