Show that the Petersen graph is a unit-distance graph. Here is also a seemingly easier question: Is there a positive integer k such that every finite unit-distance graph of girth at least k has ...

I think I'm being very stupid.<BR><BR>I've setup Cacti today using a Virtual Appliance.<BR><BR>So far so good and it's monitoring just fine, but to my mind the numbers on some of the graphs don't ...

Using graphs is not just about reading off values. In real-life contexts, the intercept, gradient and area underneath the graph can have important meanings such as a fixed charge, speed or ...

Parallel work has scrutinised the geodetic properties of unit graphs associated with rings of orders p and p², thereby extending the reach of algebraic graph theory and forging novel links ...
