Distinguished filtrations of the $0$ -Hecke modules for dual immaculate quasisymmetric functions

So-Yeon Lee, Young-Tak Oh

Let $I^\pm$ range over the set of compositions. Dual immaculate quasisymmetric functions $S_{I^} \pm^{*}$ , introduced by Berg, Bergeron, Saliola, Serrano, and Zabrocki, provide a q…

Regular Schur labeled skew shape posets and their 0-Hecke modules

Young-Hun Kim, So-Yeon Lee, Young-Tak Oh

Assuming Stanley's $P$ -partition conjecture holds, the regular Schur labeled skew shape posets with underlying set ${1, 2, \dots, n}$ are precisely the posets $P$ such that the $P…
