On the maximal energy among orientations of a tree
The trace norm of a digraph is the trace norm of its adjacency matrix, i.e. the sum of its singular values. Given a bipartite graph $G$, it is well known that the sink-source orientations have minimal trace norm among all orientations of $G$. In this paper we show that the balanced orientations of...
