Graph invariants
WebMay 21, 2024 · One of the oldest and well-studied distance-based graph invariants associated with a connected graph G is the Wiener number W ( G ), also termed as Wiener index (WI) in chemical or mathematical chemistry literature, which is defined [ 35] as the sum of distances over all unordered vertex pairs in G, namely, WebGraph invariants are properties like vertices, edges, diameter, and degree.

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. WebGraph invariants provide a powerful analytical tool for investigation of abstract …
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. WebJan 1, 2024 · Formally, those properties are called invariants; to define them, we first …
