报告摘要：
It is well known that Catalan numbers andcentral binomial coefficients have closed connection. In this talk, weintroduce a new family of two-parametric Catalan numbers which can unifyCatalan numbers, k-central binomial coefficients, the shifted and scaledcentral binomial coefficients, and Patalan numbers. For the two-parametricCatalan numbers, we study their combinatorial interpretation, shifted Hankeldeterminant and Stieltjes moment property. Furthermore, we give a combinatorialinterpretation for two-parametric binomial coefficients by Chung-Feller theorem,which in particular answers a question of Straub and Moll concerning k-central binomialcoefficients.
