WebDec 27, 2024 · A vertex v and an edge e = {vi, vj} in a graph G are incident if and only if v ∈ e. Example 5.2.6: Vertex Incident with Edge. Vertex A is incident with edge {A, B} in the graph in Figure 5.2.11, that is, A is in the edge. Definition \PageIndex {7}: Degree. The degree of a vertex v is the number of edges incident with v. In discrete mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related". The objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of … See more Definitions in graph theory vary. The following are some of the more basic ways of defining graphs and related mathematical structures. Graph A graph … See more Two edges of a graph are called adjacent if they share a common vertex. Two edges of a directed graph are called consecutive if the head of the first one is the tail of the second one. Similarly, two vertices are called adjacent if they share a common edge (consecutive … See more There are several operations that produce new graphs from initial ones, which might be classified into the following categories: • unary operations, which create a new graph from an initial … See more • Conceptual graph • Graph (abstract data type) • Graph database • Graph drawing • List of graph theory topics See more Oriented graph One definition of an oriented graph is that it is a directed graph in which at most one of (x, y) and (y, x) may be edges of the graph. That is, it is a directed graph that can be formed as an orientation of an undirected (simple) … See more • The diagram is a schematic representation of the graph with vertices $${\displaystyle V=\{1,2,3,4,5,6\}}$$ and edges • In computer science, directed graphs are used to represent knowledge (e.g., conceptual graph), finite state machines, … See more In a hypergraph, an edge can join more than two vertices. An undirected graph can be seen as a simplicial complex consisting of 1-simplices (the edges) and 0-simplices (the vertices). As such, complexes are generalizations of graphs since they … See more

Directed and Undirected graph in Discrete Mathematics
WebDiscrete mathematics refers to both finite and countable phenomena, including the two central topics combinatorics (advanced counting and arrangements) and graph theory ( the mathematics of networks) and important contemporary examples include the study of social networks, analysis of efficiency of algorithms, combinatorial design of experiments, as … WebThe graph is a mathematical and pictorial representation of a set of vertices and edges. It consists of the non-empty set where edges are connected with the nodes or vertices. The nodes can be described as the vertices that correspond to objects. The edges can be referred to as the connections between objects. WebA graph is a collection of points and lines between those points.
