چکیده
|
for a simple connected graph g with n vertices and m edges, let g→ be a digraph obtained by giving an arbitrary direction to the edges of g. in this paper, we consider the skew laplacian/skew adjacency matrix of the digraph g→. we obtain upper bounds for the skew laplacian/skew adjacency spectral radius, in terms of various parameters (like oriented degree, average oriented degree) associated with the structure of the digraph g→. we also obtain upper and lower bounds for the skew laplacian/skew adjacency spectral radius, in terms of skew laplacian/skew adjacency rank of the digraph g→.
