On the magnitude of the roots of some well-known enumerative polynomials

Acta Mathematica Hungarica volume 159, pages 257–264 (2019)Cite this article

Abstract

We present estimations of the roots of r-Dowling, r-Lah and r-Dowling–Lah polynomials. It is known that these polynomials have simple, real and non-positive roots. We give bounds for them and we also compute the real magnitude of the roots via computational methods.
