Spectral extremal results on the -index of graphs without minors and star forests
Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang
Let be a graph of order , and let and be the adjacency matrix and the degree matrix of respectively. Define the convex linear combinations of $A (…
The signless Laplacian spectral radius of graphs without intersecting odd cycles
Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang
Let be a graph consisting of cycles of odd length , respectively which intersect in exactly a common vertex, where and $a_1\g…
On the spectral radius of graphs without a star forest
Ming-Zhu Chen, A-Ming Liu, Xiao-Dong Zhang
In this paper, we present two sharp upper bounds for the spectral radius of (bipartite) graphs with forbidden a star forest and characterize all extremal graphs. Moreover, the mini…
A -covering subgroup system of a finite group for some classes of -soluble groups
A-Ming Liu, W. Guo, Inna N. Safonova +1
Let be a class of group and a finite group. Then a set of subgroups of is called a \emph{-covering subgroup system} for the class if $G\in {\…
The Cohen-Macaulay Property of -ideals
A-Ming Liu, Jin Guo, Tongsuo Wu
For positive integers , let where . For a pure -simplicial complex such that an…
On a generalisation of finite -groups
Chi Zhang, Wenbin Guo
Let is some partition of all primes and a finite group. A subgroup of is said to be -subnormal in if there exists a subgroup cha…
