The theorem by Fried and MacRae yields a way to prove the following fact for nonconstant functions f, g from mathbbC{mathbb{C}} to mathbbC{mathbb{C}} : if both the composition f °g{f circ g} and g are polynomial functions, then f has to be a polynomial function as well. We ...
An interpretation of an L-sequent G into an L-model M = (W, R, V ) is a function I : Lab(G) → W such that the following conditions apply whenever the respective type of labels exists in G: 1. I(•) = ρ, where ρ is the root of M; 2. I(•)R I(•i) for ...

Equality of the two completes our proof. ◻ Take singleton set {0}, some set N , and a function suc:{0}∪N→{0}∪N . We require that suc is injective and that suc({0}∪N)=N . Moreover, we define suc|{0}:{0}→N,suc|{0}|(0)=suc(0). Definition 1.7 A magma is ...
