Ramanujan sums and rectangular power sums
John Shareshian, Sheila Sundaram
For a fixed nonnegative integer and positive integer , we investigate the symmetric function \[\sum_{d|n} \left(c_d(\tfrac{n}{d})\right)^u p_d^{\tfrac{n}{d}},\] where …
Moments of Colored Permutation Statistics on Conjugacy Classes
Jesse Campion Loth, Michael Levet, Kevin Liu +2
In this paper, we consider the moments of statistics on conjugacy classes of the colored permutation groups . We first show that…
Topology of Cut Complexes of Graphs
Margaret Bayer, Mark Denker, Marija Jelić Milutinović +3
We define the -cut complex of a graph with vertex set to be the simplicial complex whose facets are the complements of sets of size in inducing disconnecte…
Permutation Statistics in Conjugacy Classes of the Symmetric Group
Jesse Campion Loth, Michael Levet, Kevin Liu +3
We introduce the notion of a weighted inversion statistic on the symmetric group, and examine its distribution on each conjugacy class. Our work generalizes the study of several co…
Pieri rules for skew dual immaculate functions
Elizabeth Niese, Sheila Sundaram, Stephanie van Willigenburg +1
In this paper we give Pieri rules for skew dual immaculate functions and their recently discovered row-strict counterparts. We establish our rules using a right-action analogue of…
On Sums, Derivatives, and Flips of Riordan Arrays
Caroline Bang, Matias von Bell, Eric Culver +4
We study three operations on Riordan arrays. First, we investigate when the sum of Riordan arrays yields another Riordan array. We characterize the - and -sequences of these…
