NO Non-Confluence Proof

Non-Confluence Proof

by ACP

Input

The rewrite relation of the following TRS is considered.

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

Proof

1 Non-Joinable Fork

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

t0 = h(c,a)
2 h(c,f(a))
= t1

t0 = h(c,a)
ε b
= t1

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