Consider a graph without self-loops. Suppose you can't see it, but you're told the degree of every node. Can you recreate it? In many cases the answer is "no," because the degree contains no information about which node a particular edge connects to. So the real question is this: should we pay attention to which node a self-loop …

WebI understand that a regular graph is a graph where all nodes have the same degree. I'm interested in a slightly stronger property: all nodes have the same local topology. What I mean by this is: no matter what node I stand at, I see the same number of neighbours (hence regularity), but I also see the same connections among neighbours, and the ...

WebMar 24, 2024 · A graph H is an induced minor of a graph G if H can be obtained from G by vertex deletions and edge contractions.
