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 . 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 with cardinality 5: classification and enumeration
William Q. Erickson, Nicholas B. Jones
Two subsets of 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…
Expected value and a Cayley-Menger type formula for the generalized earth mover's distance
William Q. Erickson
The earth mover's distance (EMD), also known as the 1-Wasserstein metric, measures the minimum amount of work required to transform one probability distribution into another. The E…
