报告内容:

Abstract. I will present Stieltjes-type and Jacobi-type continued fractions for some master polynomials that enumerate permutations, set partitions or perfect matchings with a large  (sometimes infinite) number of simultaneous statistics.These results contain many previously obtained identities as special cases, providing a common refinement of all of them.  This talk is based on joint work with Alan Sokal.
