Uniqueness of Algebroid Functions Concerning Nevanlinna’s five-value Theorem on Annuli

Abstract

In this paper, we prove a uniqueness theorem of derivative’s of algebroid functions on annuli which improve and generalize the Navenlinna’s five-value theorem for algebroid functions on annuli.

Key words and phrases. Value distribution theory; Nevanlinna theory; algebroid functions; sharing values and uniqueness; annuli.
