Functional identities of degree 2 at two-sided zero products on incidence algebras

Hongyu Jia, Zhankui Xiao

Let $R$ be a commutative ring with unity such that $\frac{1}{2} \in R$ . Let $X$ be a connected finite poset with $∣ X ∣ > 2$ and $I (X, R)$ be the incidence algebra of $X$ over $R$ . In th…

A categorification of the Brenti--Welker identity

Deke Zhao, Zhankui Xiao

The paper aims to provide a categorification of the Brenti--Welker identity involving Eulerian numbers in (Adv. Appl. Math. 42 (2009): 545--556) by lifting it from an enumerative e…
