摘要:
The theory of H-sets was first propounded by L. Collatz [3] and [4]. This concept has been shown to be useful in the study of uniform approximation, and we here consider the form H-sets take in this setting of vector-valued functions and prove a general characterization theorem. A similar exposition for the linear real-valued case can be found in [1].
