on the skew spectral moments of graphs
let $g$ be a simple graph, and $g^{sigma}$ be an oriented graph of $g$ with the orientation $sigma$ and skew-adjacency matrix $s(g^{sigma})$. the $k-$th skew spectral moment of $g^{sigma}$, denoted by $t_k(g^{sigma})$, is defined as $sum_{i=1}^{n}( lambda_{i})^{k}$, where $lambda_{1}, lambda_{2},cdots, lambda_{n}$ are the eigenvalues of $g^{sigma}$. suppose $g^{sigma...
متن کاملSpectral characterization of graphs with index
A graph is said to be determined by the adjacency spectrum (DS for short) if there is no other nonisomorphic graph with the same spectrum. All connected graphs with index at most √ 2 + √ 5 are known. In this paper, we show that with few exceptions all of these graphs are DS. AMS Subject Classification: 05C50.

In the paper, we prove that all generalized cocktail-party graphs with order at least 23 are determined by their adjacency spectra.
متن کاملSpectral Characterization of Some Generalized Odd Graphs
Suppose G is a connected, k-regular graph such that Spec G Spec G where G is a distance-regular graph of diameter d with parameters a1 a2 adÿ1 0 and ad > 0; i.e., a generalized odd graph, we show that G must be distance-regular with the same intersection array as that of G in terms of the notion of Ho ̈man Polynomials. Furthermore, G is isomorphic to G if G is one of the odd polygon ...
متن کاملGeneralized Spectral Characterization of Graphs Revisited
A graph G is said to be determined by its generalized spectrum (DGS for short) if for any graph H, H and G are cospectral with cospectral complements implies that H is isomorphic to G. Wang and Xu (2006) gave some methods for determining whether a family of graphs are DGS. In this paper, we shall review some of the old results and present some new ones along this line of research. More precisel...
