Palindromicity of the numerator of a statistical generating function

Rebecca Bourn, William Q. Erickson

We prove a conjecture of Bourn and Willenbring (2020) regarding the palindromicity and unimodality of a certain family of polynomials $N_{n} (t)$ . These recursively defined polynomial…

Dimension identities, almost self-conjugate partitions, and BGG complexes for Hermitian symmetric pairs

William Q. Erickson, Markus Hunziker

An almost self-conjugate (ASC) partition has a Young diagram in which each arm along the diagonal is exactly one box longer than its corresponding leg. Classically, the ASC partiti…

Homometric subsets of $Z_{n}$ with cardinality 5: classification and enumeration

William Q. Erickson, Nicholas B. Jones

Two subsets of $Z_{n}$ are said to be homometric if they have the same multiset of pairwise cyclic (i.e., Lee) distances. Homometric subsets necessarily have the same cardin…
