摘要
Let TR be the class of functions f(z) with f(0) = 0 and f′(0) = 1 that are regular and typically real in the disk |z| < 1. The region of values of the system {f{z0), f(r), f″(0)/2} (for fixed z0 and r, 0 < r < 1, on the class TR is determined. The region of values of f(z0) on the class of functions from TR with fixed f(r) and f″(0) is found. ©1999 Kluwer Academic/ Plenum Publishers.
