Graph invariants

WebThere are many examples of graph parameters, specially based on distances which are applicable in chemistry. The Wiener index is probably the most studied graph invariant in both theoretical and practical meanings (cf. [4,6–11,22]). Apart from the Wiener index, we will consider some other related indices. WebMay 22, 2024 · One can invent all kinds of silly functions which aren't graph invariants. For example, define $S (G) = 1$ if $1$ and $2$ are nodes of $G$ and there is an edge from $1$ to $2$, and $0$ otherwise. But the only functions we care about are those which respect graph isomorphism. Share Cite Follow edited May 22, 2024 at 22:46

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 . 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.
