Counterexamples regarding elementary symmetric partitions

Vixail Hadelyn, Harper Niergarth, Weiyou Li +1

Ballantine, Beck, and Merca defined the elementary symmetric partition map pre $_{j}$ that sends a partition $λ$ to a larger partition whose parts are the summands appearing in the ev…

Positive expansions of permuted basement and quasisymmetric Macdonald polynomials at $t = 0$

Olya Mandelshtam, Harper Niergarth, Kartik Singh

It is well known that the $q$ -Whittaker polynomials, which are $t = 0$ specializations of the Macdonald polynomials $P_{λ} (X; q, t)$ , expand positively as the sum of Schur polynomials. M…
