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, WebJan 25, 2024 · An invariant based on the number of vertices at each distance from each vertex will work well on random regular graphs, but fail completely on strongly regular graphs or incidence geometries. And so on. There is also the question of …
WebIn the context of graph isomorphism testing, so-called complete graph invariants have been investigated [9,11]. Such a graph invariant has the property that it discriminates all non-isomorphic graphs uniquely (i.e., without any degeneracy) and isomorphic graphs are mapped to equal values [9,11]. WebAsymptotics of the relative Reshetikhin-Turaev invariants - Ka Ho WONG 黃嘉豪, ... Branching random walks (BRW) on groups consist of two independent processes on the Cayley graphs: branching and movement. Start with a particle on a favorite location of the graph. According to a given offspring distribution, the particles at the time n split ...
WebInvariants are used in diverse areas of mathematics such as geometry, topology, algebraand discrete mathematics. 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. WebThis book includes a number of research topics in graph the-ory and its applications. The topics are in the form of research projects developed by the author over the last 15 years. We dis-cuss various research ideas devoted to -discrepancy, strongly perfect graphs, the reconstruction conjectures, graph invariants,
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 .
