THE REGION OF VALUES OF THE SYSTEM {f(z_1),..., f(z_n)} IN THE CLASS OF TYPICALLY REAL FUNCTIONS

摘要

The paper studies the region of values of the system {f(z_1), f(z_2), ..., f(z_n)} in the class T of functions f(z) = z + a_2z~2 + • • • regular in the unit disk and satisfying the condition Im f(z) Im z > 0 for Im z ≠ 0.
