Let X be a Banach space, D an open subset of X and Y a complete metric space. Assume that Y is metrically convex. For closed, locally m-expansive and mapping open subsets of D onto open subsets of Y, is is shown that y ∊ T(D) if and only if there exists x 0 ∊ D such that d(Tx 0, y) ≤ d(Tx, y) for all x ≤ ∂D.
