We are asked to determine termination of the following first-order TRS. f : [o] --> o g : [o] --> o f(f(X)) => g(f(X)) We use rule removal, following [Kop12, Theorem 2.23]. This gives the following requirements (possibly using Theorems 2.25 and 2.26 in [Kop12]): f(f(X)) >? g(f(X)) We orient these requirements with a polynomial interpretation in the natural numbers. The following interpretation satisfies the requirements: f = \y0.1 + 2y0 g = \y0.y0 Using this interpretation, the requirements translate to: [[f(f(_x0))]] = 3 + 4x0 > 1 + 2x0 = [[g(f(_x0))]] We can thus remove the following rules: f(f(X)) => g(f(X)) All rules were succesfully removed. Thus, termination of the original system has been reduced to termination of the beta-rule, which is well-known to hold. +++ Citations +++ [Kop12] C. Kop. Higher Order Termination.
