چکیده
|
Let g be a simple graph with n vertices and with the seidel matrix s. suppose μ1, μ2,..., μn are the seidel eigenvalues of g. the estrada index of the seidel matrix of g is defined as see(g)=sum_{i=1}^{n} eμi. in this paper, we compute the estrada index of the seidel matrix of some known graphs. also, some bounds for the seidel energy of graphs are given.
