Abstract: In this talk, we mainly discuss the zeros distribution of three recurrence sequences. As applications, we obtain the weakly (Hurwitz) stable of the reverse strong Turan expressions of Bell polynomials, Dowling polynomials, and associated Lah polynomials. And the reverse reverse strong Turan expressions of Delannoy polynomials, Morgan-Voyce polynomials, some independence polynomials and sextet polynomials have only real zeros respectively. Finally, we give some open problems related to the Eulerian polynomials and Narayana polynomials. (Joint work with Xue Yan)
