Abstract: |
In this paper, uniqueness of entire function related to shared set is studied. Let $f$ be a non-constant entire function and $k$ be a positive integer, $d$ be a finite complex number. There exists a set $S$ with 3 elements such that if $f$ and its derivative $f^{(k)}$ satisfy $E(S,f)=E(S,f^{(k)})$, and the zeros of $f(z)-d$ are of multiplicity $\geq k 1$, then $f=f^{(k)}$. |
