distribution of descents in matchings and derangements
abstract:
the distribution of descents in certain conjugacy classes of $s_n$ have been previously studied, and it is shown that its moments have interesting properties. this talk provides a bijective proof of the symmetry of the descents and major indices of matchings and uses a generating function approach to prove a central limit theorem for the number of descents in matchings. we also extend this result to derangements.
