Abstract
Let be the skew-adjacency matrix of the oriented graph , which is obtained from a simple undirected graph by assigning an orientation to each of its edges. The skew energy of an oriented graph is defined as the sum of absolute values of all eigenvalues of . For any positive integer with , we determine the graph with minimal skew energy among all oriented bicyclic graphs that contain no vertex disjoint odd cycle of lengths and with on vertices with a given diameter .
