WebbTheorem 5.2 (Tietze extension theorem for metric spaces) Let A be a closed subset of a metric space X, and let f: A ! [a;b] ˆ R be a bounded continuous function. Then there exists a continuous function g: X ! [a;b] that extends f (i.e. g A = f). Since we can always take a = inf x2A f(x) and b = sup x2A f(x), this result says that we can Webb1977] SOME EXTENSIONS OF THE TIETZE-URYSOHN THEOREM 437 First proof of Theorem D: We begin by reducing the problem to the special case where only compact …
