Sekundarni naslov: | Medianski in kvazimedianski direktni produkti grafov |
Sekundarni povzetek: | Median graphs are characterized among direct products of graphs on at least three vertices. Beside some trivial cases, it is shown that one component of ▫$G \times P_3$▫ is median if and only if ▫$G$▫ is a tree in that the distance between any two vertices of degree at least 3 is even. In addition, some partial results considering median graphs of the form ▫$G \times K_2▫$ are proved, and it is shown that the only nonbipartite quasi-median direct product is ▫$K_3 \times K_3$▫. |
