On the graphs having at most one positive eccentricity eigenvalue

Sezer Sorgun, Hakan Küçük

The eccentricity (anti-adjacency) matrix $ε (G)$ of a graph $G$ is obtained from the distance matrix by retaining the eccentricities in each row and each column. This matr…

On the spectral characterization of mixed extensions of $P_{3}$

Willem H. Haemers, Sezer Sorgun, Hatice Topcu

A mixed extension of a graph $G$ is a graph $H$ obtained from $G$ by replacing each vertex of $G$ by a clique or a coclique, whilst two vertices in $H$ corresponding to distinct ve…

On the spectral characterization of Kite graphs

Sezer Sorgun, Hatice Topcu

The \textit{Kite graph}, denoted by $K i t e_{p, q}$ is obtained by appending a complete graph $K_{p}$ to a pendant vertex of a path $P_{q}$ . In this paper, firstly we show that no two…
