Affine Equivalence
Two \((m,n,p)\)-functions \(f(x)\) \(g(x)\) and are called affine equivalent if there exits affine polynomials \(A_1(x)\) and \(A_2(x)\) such that:
\[ g(x)=A_1 \circ f \circ A_2(x) \] (sidenote: We have the following implication: Affine equivalence \(\implies\) linear equivalence )
