报告题目:Positivity and log-convexity problems of three-term recurrence sequences报告摘要:We first present some criteria for the positivity and log-convexity of three-term recurrence sequences, and then apply them to Apery-like numbers...[详细]
报告题目:Zero-sum problems on finite abelian groups with large exponents报告摘要:Let G be a finite abelian group with a larger exponent exp(G) compare to, and let k be a positive integer. In this talk, we will present some recent struc...[详细]
报告题目:The (e)-positivity of two kinds of claw-free graphs报告摘要:This talk continues our work on Stanley and Stembridge's 3+1 conjecture - the chromatic symmetric function of every claw-free interval graph is e-positive. We focus o...[详细]
