报告摘要:In this talk, we will report some developments in analytic properties of combinatorial sequences. These properties include unimodality, log-concavity, log-convexity, Polya Frequency, Stieltjes moment properties, total positivity of matrices and polynomials with only real zeros. They often arise in combinatorics and Analysis, Algebra and Geometry, Probability and Statistics, and so on.
