Hilbert functions of filtered graphical zonotopal algebras

Boris Shapiro, Ilya Smirnov, Arkady Vaintrob

The external zonotopal algebra of a graph is generated by nilpotent vertex elements $X_{v}$ and determines the graphical matroid after deleting loops. Replacing these generators by $…

On the number of principal ideals in d-tonal partition monoids

Chwas Ahmed, Paul Martin, Volodymyr Mazorchuk

For a positive integer $d$ , a non-negative integer $n$ and a non-negative integer $h \leq n$ , we study the number $C_{n}^{(d)}$ of principal ideals; and the number $C_{n, h}^{(d)}$ o…
