Non-Confluence Proof

by ACP

Input

The rewrite relation of the following TRS is considered.

c f(h(b,b))
c b
b b
c a

Proof

1 Non-Joinable Fork

The system is not confluent due to the following forking derivations.

t0 = c
ε a
= t1

t0 = c
ε b
= t1

The two resulting terms cannot be joined for the following reason:
