报告摘要:  Positivity (for example, log-concavity, log-convexity, q-log-convexity, and total positivity)  of sequences  arises often in combinatorics, algebra, geometry, analysis, probability and statistics and has been extensively investigated. In this talk, I will report  some recent development in combinatorics.
