Zeros distribution of the reverse strong Turan expressions of polynomials sequences

In this paper, we first show the zeros distribution of the reverse strong Turan expressions of three recurrence polynomials se-quences. Then as applications, we obtain the weak (Hurwitz) stability of the reverse strong Turan expressions of Bell poly-nomials, Dowling polynomials, ordered Bell polynomials, or-dered Dowling polynomials and associated Lah polynomials respectively. On the other hand, the reverse strong Turan ex-pressions of Delannoy polynomials, Morgan-Voyce polynomi-als, many independence polynomials and sextet polynomials have only real zeros respectively. Finally, we present some con-jectures related to the Eulerian polynomials and the Narayana polynomials.(c) 2022 Elsevier Inc. All rights reserved.
