Streszczenie
We investigate the uniqueness of entire functions sharing values or small functions with their derivatives. One of our results gives a necessary condition on the Nevanlinna deficiency of the entire function $f$ sharing one nonzero finite value CM with its derivative $f'$. Some applications of this result are provided. Finally, we prove some further results on small function sharing.
