Sekundarni naslov: | Vzajemna vidnost v krepkih produktih grafov skozi celotno medsebojno vidnost |
Sekundarni povzetek: | Let ▫$G$▫ be a graph and ▫$X\subseteq V(G)$▫. Then ▫$X$▫ is a mutual-visibility set if each pair of vertices from ▫$X$▫ is connected by a geodesic with no internal vertex in ▫$X$▫. The mutual-visibility number ▫$\mu(G)$▫ of ▫$G$▫ is the cardinality of a largest mutual-visibility set. In this paper, the mutual-visibility number of strong product graphs is investigated. As a tool for this, total mutual-visibility sets are introduced. Along the way, basic properties of such sets are presented. The (total) mutual-visibility number of strong products is bounded from below in two ways, and determined exactly for strong grids of arbitrary dimension. Strong prisms are studied separately and a couple of tight bounds for their mutual-visibility number are given. |
