Abstract

This paper has a twofold purpose. The first is to establish a second main theorem for meromorphic functions on the complex disc Δ(R0) ⊂ ℂ with finite growth index and small functions, where the counting functions are truncated to level 1 and the small term is more detailedly estimated. The second is to prove a generalization and improvement of the five values theorem of Nevanlinna for the case of five small functions on the complex disc Δ(R0).
