报告摘要：In this talk, we introduce our results for the real stability and the Hurwitz stability, which generalize the real-rootedness and the strong q-log-convexity of polynomials sequences respectively. As applications, we obtain the real stability of many important multivariate polynomials, such as multivariate Eulerian polynomials, multivariate Bell polynomials and multivariate polynomials over Stirling permutations in a unified manner. And we also show the zeros distribution of the reverse strong Turan expressions of Bell polynomials, Dowling polynomials, several independence polynomials and sextet polynomials.
