Non-Confluence Proof

Input

The rewrite relation of the following TRS is considered.

a(x) g(b(x))
a(x) c(x)
b(x) g(b(x))

Proof

1 Non-Joinable Fork

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

t0 = a(c_1)
ε g(b(c_1))
= t1

t0 = a(c_1)
ε c(c_1)
= t1

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