Time : 2014-07-17 (Thu) 15:00 - 16:00
Place : Lecture Hall, Inst. of Mathematics
Abstract: Sorting indices of type A,B,D are defined by Petersen, while the concept of set-valued equidistribution for type A is introduced by Foata and Han. For type B, the set-valued equildistribution for statistics involving sorting index is investigated by Chen et al. In this talk we introduce the sorting index and find many new multi-variable set-valued equildistributions over type A, B, and D and others. Generating functions are also derived.
