Abstract: We study oriented weighted graphs and their edge ideals. We consider the problem of characterizing the unmixedness of the edge ideals. This is a natural extension of the well-covered property of simple graphs to oriented weighted graphs. We also consider the Cohen-Macaulayness of these graphs.
