## Abstract Let β Β· β denote the uniform norm in the unit disk of the complex plane β. The main result in this note is as follows: __For any complex polynomial P of degree at most n and any Ξ±__ β β __the inequality__ β__P__ β β©½ (__n__ + 1)(β__z P__ (__z__) + __Ξ±__ β β |__Ξ±__ |) __holds.__ For any
