A result related to the Sendov conjectureThe Sendov conjecture asserts that if $p(z) = \prod_{j=1}^{N}(z-z_j)$ is a
polynomial with zeros $|z_j| \leq 1$, then each disk $|z-z_j| \leq 1$ contains
a zero of $p'$. Our purpose is the following: Given a zero $z_j$ of order $n
\geq 2$, determine whether there exists $ζ\not= z_j$ such that $p'(ζ)
= 0$ and $|z_j - ζ| \leq 1$. In this paper we present some partial results
on the problem.
