On functions of bounded rotation

J. W. Noonan
1972 Proceedings of the American Mathematical Society  
For fixed »c^2, denote by Vk and Rk the classes of functions regular in the unit disc and having boundary and radial rotation, respectively, at most k-n. The concept of order of a function is defined for both Vk and Rk. For functions in these classes, the growth of integral and coefficient means is studied in terms of the order of the function. Some length-area results are also obtained.
