| contents | We prove Dual Smale's mean value conjecture for all odd polynomials with nonzero linear term. Precisely, if $P$ is an odd polynomial of degree $d\ge3$ with $P(0)=0$ and $P'(0)=1$, then there exists a critical point $ζ$ of $P$ such that $$ \left|\frac{P(ζ)}ζ\right| \ge \frac1d. $$This result can be regarded as a dual counterpart of T. W. Ng's theorem on Smale's mean value conjecture for odd polynomials with nonzero linear term [J. Aust. Math. Soc. 75 (2003), 409--411]. |
