Non-uniform pairwise cross $t$ -intersecting families

Yongjiang Wu, Yongtao Li, Tingzeng Wu +1

Let $n \geq t \geq 1$ and $A_{1}, A_{2}, \dots, A_{m} \subseteq 2^{[n]}$ be non-empty families. We say that they are pairwise cross $t$ -intersecting if $|A…

Immanantal polynomials of the linear combination matrices of graphs

Xiangshuai Dong, Tingzeng Wu

In this paper, we focus on the study of immanantal polynomials for linear combination matrices composed of the degree matrix and adjacency matrix of a graph. First, applying the co…

Hook immanantal equalities for linear combination matrices of (di)graphs and their applications

Xiangshuai Dong, Tingzeng Wu, HongJian Lai

Let $I ¨ _{I^} »$ be an irreducible character of the symmetric group $S_{n}$ . For an $n \times n$ matrix $M = (m_{ij})$ , define the immanant of $M$ corresponding to $I ¨ _{I^} »$ by \begin{eqnar…

On the edge reconstruction of the second immanantal polynomials of undirected graph and digraph

Tingzeng Wu

Let $M = (m_{ij})$ be an $n \times n$ matrix. The second immanant of matrix $M$ is defined by \begin{eqnarray*} d_{2}(M)=\sum_{Ï\in S_{n}}Ï_{2}(Ï)\prod_{s=1}^{n}m_{sÏ(s)}, \end{eq…

Brualdi-Goldwasser-Michael problem for maximum permanents of {\rm(0,1)}-matrices

Tingzeng Wu, Xiangshuai Dong, Huazhong LÃ¼

Let $U (n, I ¨ )$ be the set of all {\rm(0,1)}-matrices of order $n$ with exactly $I ¨ $ 0's. Brualdi et al. investigated the maximum permanents of all matrices in $\mathscr{U}…
