Graph invariants

WebJan 1, 2024 · A V -valued graph invariant (Lovász 2012) is any function \pi : {\mathscr G} \to V such that G ≅ H implies π ( G) = π ( H ): a graph invariant is a property of a graph that does not depend on its actual representation (i.e., on the names of its nodes) but only on the graph structure. WebGraph invariants are properties of graphs that are invariant under graph isomorphisms: each is a function such that () = whenever and are isomorphic graphs. Examples include the number of vertices and the number of edges.

Some important classes of transformations are defined by an invariant they leave unchanged. For example, conformal mapsare defined as transformations of the plane that preserve angles.

WebIn this paper extremal values of the difference between several graph invariants related to the metric dimension are studied: Mixed metric dimension, edge metric dimension and strong metric dimension. These non-trivial extremal values are computed over all connected graphs of given order. 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.
