报告摘要：In this talk, we focus on studying certain phenomenons stemmed from the Pascal triangle, and then present four topics involving the David rule and the (weighted) sums of 2×2 minors or permanents of Riordan arrays related to weighted partial Motzkin paths. When the weight parameters are specialized, several new identities are obtained related to some classical sequences involving Catalan numbers. With the help of the computer algebra package “HolonomicFunctions”, we further derive some new identities involving generalized Narayana polynomials.
