Functions regular in the unit circle
C. N. Linden, M. L. Cartwright · Mathematical Proceedings of the Cambridge Philosophical Society · 1956
Let be a function regular for | z | 1, the bounds on each circle | z | = r are given respectively by K(α) being a constant which depends only on the corresponding value of α which occurs in (1). We shall always use the symbols K and A to represent constants dependent on certain parameters such as α, not necessarily having the same value at each occurrence.
