Dear Colleagues, Carbon allotropes are basically distinguished by the way in which carbon atoms are linked to each other, forming different types of networks (graphs) of carbon atoms. Different structures are builds with sp2-hybridized carbon atoms like PAHs, graphite, nanotubes, nanocones, nanohorns, and …

WebNov 18, 2024 · The Basics of Graph Theory. 2.1. The Definition of a Graph. A graph is a structure that comprises a set of vertices and a set of edges. So in order to have a … In graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. Any cut determines a cut-set, the set of edges that have one endpoint in each subset of the partition. These edges are said to cross the cut. In a connected graph, each cut-set determines a unique cut, and in some cases … See more A cut C = (S,T) is a partition of V of a graph G = (V,E) into two subsets S and T. The cut-set of a cut C = (S,T) is the set {(u,v) ∈ E u ∈ S, v ∈ T} of edges that have one endpoint in S and the other endpoint in T. If s … See more A cut is maximum if the size of the cut is not smaller than the size of any other cut. The illustration on the right shows a maximum cut: the … See more The family of all cut sets of an undirected graph is known as the cut space of the graph. It forms a vector space over the two-element finite field of arithmetic modulo two, with the symmetric difference of two cut sets as the vector addition operation, and is the See more A cut is minimum if the size or weight of the cut is not larger than the size of any other cut. The illustration on the right shows a minimum … See more The sparsest cut problem is to bipartition the vertices so as to minimize the ratio of the number of edges across the cut divided by the number of vertices in the smaller half of the partition. This objective function favors solutions that are both sparse (few edges … See more • Connectivity (graph theory) • Graph cuts in computer vision • Split (graph theory) • Vertex separator • Bridge (graph theory) See more

WebIn graph theory, a cut is a partition of the vertices of a graph into two disjoint subsets. Any cut determines a cut-set, the set of edges that have one endpoint in each subset of the … A connected component is a maximal connected subgraph of an undirected graph. Each vertex belongs to exactly one connected component, as does each edge. A graph is connected if and only if it has exactly one connected component. The strong components are the maximal strongly connected subgraphs of a directed graph. A vertex cut or separating set of a connected graph G is a set of vertices whose removal render…
WebA connected graph G may have at most (n-1) cut edges. Removing a cut edge may leave a graph disconnected. Removal of an edge may increase the number of components in a graph by at most one. A cut edge 'e' must not be the part of any cycle in G. If a cut edge exists, then a cut vertex must also exist because at least one vertex of a cut edge is ...
