Abstract

In this paper, we obtain some results concerning annular regions containing all the zeros of a given polynomial. These annular regions have radii in terms of the Bell numbers, Pell numbers, Stirling numbers, Fibonacci numbers, Motzkin numbers, Catalan numbers, and/or the Schr¨oder numbers. Also, we show, by means of examples, that for some polynomials our results sharpen some of the known results in this direction.
