Certification Problem

Input (COPS 69)

We consider the TRS containing the following rules:

F(x,y) c(A) (1)
G(x) x (2)
h(x) c(x) (3)

The underlying signature is as follows:

{F/2, c/1, A/0, G/1, h/1}

Property / Task

Prove or disprove confluence.

Answer / Result

Yes.

Proof (by ACP @ CoCo 2021)

1 Strongly closed

Confluence is proven since the TRS is strongly closed. The joins can be performed using 0 step(s).
