In other words, for the point set mentioned, it is a unit distance graph.

WebJan 22, 2014 · Any graph gives rise to an \mathbb {N} -enriched category, the objects being the vertices and the homs being distances in the graph. So, we get an invariant of graphs — and that’s what’s called magnitude. WebDec 31, 2024 · The regular graphs with diameter two A well-known fact is that almost all graphs have diameter two [ 3 ]. So, we will study the relations between the E -eigenvalues and the A -eigenvalues of regular graphs with diameter two in this subsection. Recall that the maximum degree ( G) of a graph of order n is at most n − 1. dick grayson secret identity

WebAlgebraic graph theory is a branch of mathematics in which algebraic methods are applied to problems about graphs. This is in contrast to geometric, combinatoric, or algorithmic approaches. There are three main branches of algebraic graph theory, involving the use of linear algebra, the use of group theory, and the study of graph invariants .
