Commuting Functions in Class K and Families of Wandering Baker Domains.

The paper’s Theorem A states that if f,g ∈ K commute and f = g + c, then F(f) = F(g) and J(f) = J(g), and provides a two-case normality argument adapted to class K (with multiple essential singularities) to prove it . The candidate solution proves the same result by deriving the functional identity f^n = g^n + n c on suitable domains and transferring normality via divergence to ∞. This is a valid alternative route provided one carefully handles the domain-of-definition issues in class K; these details are briefly noted but could be made more explicit. Thus both are correct, with different proof styles.
