Abstract
Mixed graphs can be seen as digraphs that have both arcs and edges (or digons, that is, two opposite arcs). In this arti- cle, we consider the case where such graphs are bipartite. As main results, we show that in this context the Moore- like bound is attained in the case of diameter k = 3, and that bipartite-mixed graphs of diameter k ≥ 4 do not exist.
