Let (X‚ d) and (Y‚ ρ) be compact metric spaces‚ τ be a Lipschitz involution on (X‚ d) and η be Lipschitz involution on (Y‚ ρ). Suppose that for all x∈X‚ for all y∈Y‚, A is a real subalgebra of C(X‚ τ) which contains Lip(X‚ d‚ τ) and B is a real subalgebra of C(Y‚ η) which contains Lip(Y‚ ρ‚ η). We prove that if T:A→B is a surjetive -homogenous norm-additive in modulus map then there exists a unique bijection such that for all f∈A ‚ y∈Y and . Applying this fact‚ we show that if (X‚d) and (Y‚ρ) are compact metric spaces and is a surjective -homogenous norm-additive in modulus map then there exists a Lipschitz homeomorphism from to such that for all and y∈Ỵ
