We study posets defined by Stanley as a multiset generalization of Greene's posets of shuffles. Ehrenborg defined a quasi-symmetric function encoding for the flag f-vector, denoted F P , and we determine F P for shuffle posets of multisets, expressing it as a Schur-positive symmetric function.

Type A affine shuffles are compared with riffle shuffles followed by a cut. Although these probability measures on the symmetric group S are different, they n both satisfy a convolution property. Strong evidence is given that when the ลฝ . underlying parameter q satisfies gcd n, q y 1 s 1, the induce

The interval number i(P) of a poset P is the smallest t such that P is a containment poset of sets that are unions of at most t real intervals. For the special poset Bn(k) consisting of the singletons and k-subsets of an n-element set, ordered by inclusion, i(B~(k))---min{k,nk + 1} if In~2-kl >~ n/2
