On the maximum spectral radius of multipartite graphs
AKCE International Journal of Graphs and Combinatorics, 2020 Let be an integer. A graph is called r – partite if V admits a partition into r parts such that every edge has its ends in different parts. All of the r – partite graphs with given integer r consist of the class of multipartite graphs.

On the Laplacian spectral radius of a tree
Linear Algebra and its Applications, 2003 The Laplacian matrix of a graph is the difference of the diagonal matrix of its vertex degrees and its adjacency matrix. The Laplacian spectral radius of a graph is the largest eigenvalue of its Laplacian matrix. This paper gives upper bounds on the Laplacian spectral radius of trees, in terms of the size of a maximum matching in it, and the number of ...

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

The skew spectral radius and skew Randić spectral radius of general random oriented graphs [PDF]
Let G be a simple connected graph on n vertices, and let Gσ be an orientation of G with skew adjacency matrix S(Gσ). Let di be the degree of the vertex vi in G. The skew Randić matrix of Gσ is the n×n real skew symmetric matrix RS(Gσ)=[(RS)ij], where (RS)

Bounds for the spectral radius of positive operators [PDF]
, 2000 summary:Let $f$ be a non-zero positive vector of a Banach lattice $L$, and let $T$ be a positive linear operator on $L$ with the spectral radius $r(T)$. We find some groups of assumptions on $L$, $T$ and $f$ under which the inequalities $$ \sup \{c \geq ...

Minimizing Laplacian spectral radius of unicyclic graphs with fixed girth [PDF]
, 2002 summary:In this paper we consider the following problem: Over the class of all simple connected unicyclic graphs on $n$ vertices with girth $g$ ($n$, $g$ being fixed), which graph minimizes the Laplacian spectral radius?
