Abstract: Polynomials with only real zeros arise often in combinatorics. Our interest in such polynomials was originally due to its implication about unimodality and log-concavity. In this talk we establish some sufficient conditions to the reality of zeros of polynomial sequences satisfying certain recurrence relations and then present their applications in combinatorics.
