### Tom 77 / 2001

Annales Polonici Mathematici 77 (2001), 197-207 MSC: Primary 30E10; Secondary 47B38, 47E05. DOI: 10.4064/ap77-3-1

#### Streszczenie

We prove some conditions on a sequence of functions and on a complex domain for the existence of universal functions with respect to sequences of certain derivative and antiderivative operators related to them. Conditions for the equicontinuity of those families of operators are also studied. The conditions depend upon the $$size” of the domain and functions. Some earlier results about multiplicative complex sequences are extended.
