On values of deviations for functions meromorphic in a disk. (Russian. English summary) Zbl 1074.30519
Summary: For meromorphic functions in a circle the value $$b(a,f)$$ similar to one proposed by A. Eremenko [Complex Variables, Theory Appl. 34, No. 1-2, 83-97 (1997; Zbl 0905.30025)] who considered meromorphic functions in the whole plane is introduced and studied. Exact estimates of $$b(a,f)$$ are obtained for functions of finite and infinite order.
