Some new bounds on the spectral radius of nonnegative matrices

AIMS Mathematics, 2020
In this paper, we determine some new bounds for the spectral radius of a nonnegative matrix with respect to a new defined quantity, which can be considered as an average of average 2-row sums.

A general result on the spectral radii of nonnegative k-uniform tensors

AIMS Mathematics, 2020
In this paper, we define $k$-uniform tensors for $k\geq 2$, which are more closely related to the $k$-uniform hypergraphs than the general tensors, and introduce the parameter $r^{(q)}_{i}(\mathbb{A})$ for a tensor $\mathbb{A}$, which is the ...

Spectral and Sharp Sufficient Conditions for Graphs to Admit a Strong Star Factor

Mathematics
LetGbe a graph. An odd [1,k]-factor of a graph G is a spanning subgraph H of G such that degH(v) is odd and 1⩽degH(v)⩽k for every v∈V(G) where k is a positive odd integer. We call a spanning subgraph H of a graph G a strong star factor if every component
