Meromorphic functions that share two or three values. (English) Zbl 0712.30029
The author proves the following: Theorem: Let f and g be meromorphic functions such that f and g share 1,$$\infty$$ with the same multiplicity. If $N(\gamma,\frac{1}{f})+N(\gamma,\frac{1}{g})+2\bar N(\gamma,f)<(u+o(1))T(\gamma)\quad (\gamma \in I),$ where $$u<1$$, then $$f=g$$ or $$fg=1$$. This result is an extension of earlier results of the reviewer, Osgood, Gunderson and others.
