Further results on the permanental sums of bicyclic graphs
Tingzeng Wu, Yinggang Bai
Let be a graph, and let be the adjacency matrix of . The permanental polynomial of is defined as . The permanental sum of can be…
The characterizing properties of (signless) Laplacian permanental polynomials of bicyclic graphs
Tingzeng Wu, Tian Zhou
Let be a graph with vertices, and let and be the Laplacian matrix and signless Laplacian matrix of , respectively. The polynomial $π(L(G);x)={\rm per}(xI-L…
Some properties of Pre-topological groups
Fucai Lin, Ting Wu, Yufan Xie +1
In this paper, we pose the concepts of pre-topological groups and some generalizations of pre-topological groups. First, we systematically investigate some basic properties of pre-…
Forcing and anti-forcing polynomials of a polyomino graph
Kai Deng, Huazhong Lü, Tingzeng Wu
The forcing number of a perfect matching in a graph is the smallest number of edges inside that can not be contained in other perfect matchings. The anti-forcing number…
Unpaired many-to-many disjoint path cover of balanced hypercubes
Huazhong Lü, Tingzeng Wu
The balanced hypercube , a variant of the hypercube, was proposed as a desired interconnection network topology. It is known that is bipartite. Assume that $S=\{s_1,s_…
Fractional matching preclusion for restricted hypercube-like graphs
Huazhong Lü, Tingzeng Wu
The restricted hypercube-like graphs, variants of the hypercube, were proposed as desired interconnection networks of parallel systems. The matching preclusion number of a graph is…
