Approximation by Unimodular Functions
The theorems in this paper are all concerned with either pointwise or uniform approximation by functions which have unit modulus or by convex combinations of such functions. The results are related to, and are outgrowths of, the theorems in [4; 5; 10]. In § 1, we show that a function bounded by 1, w...
