Sequences Derived from The Symmetric Powers of ${1, 2, \dots, k}$

Po-Yi Huang, Wen-Fong Ke

For a fixed integer $k$ , we define a sequence $A_{k} = (a_{k} (n))_{n \geq 0}$ and a corresponding sparse subsequence $S_{k}$ using the cardinality of the $n$ -th symmetric power of the set $\…

Super duality and homology of unitarizable modules of Lie algebras

Po-Yi Huang, Ngau Lam, Tze-Ming To

The u-homology formulas for unitarizable modules at negative levels over classical Lie algebras of infinite rank of types gl(n), sp(2n) and so(2n) are obtained. As a consequence, w…

(G,m)-multiparking functions

Hungyung Chang, Po-Yi Huang, Jun Ma +1

The conceptions of $G$ -parking functions and $G$ -multiparking functions were introduced in [15] and [12] respectively. In this paper, let $G$ be a connected graph with vertex set $…

Some Enumerations for Parking Functions

Po-Yi Huang, Jun Ma, Jean Yeh

In this paper, let $P_{n, n + k; \leq n + k}$ (resp. $P_{n; \leq s}$ ) denote the set of parking functions $α = (a_{1}, ..., a_{n})$ of length $n$ with $n + k$ (respe. $n$ )parkin…

k-flaw Preference Sets

Po-Yi Huang, Jun Ma, Jean Yeh

In this paper, let $P_{n; \leq s; k}^{l}$ denote a set of $k$ -flaw preference sets $(a_{1}, ..., a_{n})$ with $n$ parking spaces satisfying that $1 \leq a_{i} \leq s$ for any $i$ and $…

Ordered k-flaw Preferences Sets

Po-Yi Huang, Jun Ma, Yeong-Nan Yeh

In this paper, we focus on ordered $k$ -flaw preference sets. Let $O P_{n, \geq k}$ denote the set of ordered preference sets of length $n$ with at least $k$ flaws and $\mat…
