Bicyclic graphs for which the least eigenvalue is minimum

, 2009
The spread of a graph is defined to be the difference between the greatest eigenvalue and the least eigenvalue of the adjacency matrix of the graph. In this paper we determine the unique graph with minimum least eigenvalue among all connected bicyclic ...

Extremal unicyclic and bicyclic graphs with respect to Harary index

, 2013
The Harary index is defined as the sum of reciprocals of distances between all pairs of vertices of a connected graph. In this paper, we determined the extremal (maximal and minimal) unicyclic and bicyclic graphs with respect to Harary ...

Computing the determinant of a signed graph

Open Mathematics
A signed graph is a simple graph in which every edge has a positive or negative sign. In this article, we employ several algebraic techniques to compute the determinant of a signed graph in terms of the spectrum of a vertex-deleted subgraph.

The first two maximum Sombor spectral radii of bicyclic graphs

The Sombor matrix S(G) of a graph G was introduced by Gutman in 2021, in which the (i, j)-entry is equal to $sqrt(deg^(2)(u_(i))+deg^(2)(u_(j)))$ if the vertices ui and uj are adjacent in G, and zero otherwise, where deg(ui) denotes the degree of vertex ...
