THEOREM 4. Let C be an analytic Jordan curve whose interior is denoted by D, and let A be a bounded region containing C + D. Let f(z) be analytic in D, and for each positive M let FM(z) be the (or a) function analytic and of modulus not greater than M in A for which the norm IIF(z) f(z) 11' in D is least; let 1uM denote the least value of this norm. Suppose k + a + 1/p > 0, where k is an integer and 0 < a _ 1. Then, a necessary and sufficient condition that f(z) be on C of class L,(k,a) if 0 < a < 1 and of class Z(k,p) if a = 1 is
