Note on the skew energy of oriented graphs

The skew energy of oriented graphs is defined as the‎ ‎sum of the norms of all the eigenvalues of the skew  adjacency matrix‎. ‎In this note‎, ‎we obtain some upper bounds for the skew energy of any oriented graphs‎, ‎which improve the known upper‎ ‎bound obtained by Adiga et al‎.
