Jan 2, 2017 · The trivial graph is the graph on one vertex. This graph meets the definition of connected vacuously (since an edge requires two vertices). A non-trivial connected graph is any connected graph that isn't this graph.

- Finite Graphs. A graph is said to be finite if it has a finite number of vertices and a finite number of edges. A finite graph is a graph with a finite number of vertices and edges.
- Infinite Graph: A graph is said to be infinite if it has an infinite number of vertices as well as an infinite number of edges.
- Trivial Graph: A graph is said to be trivial if a finite graph contains only one vertex and no edge. A trivial graph is a graph with only one vertex and no edges.
- Simple Graph: A simple graph is a graph that does not contain more than one edge between the pair of vertices. A simple railway track connecting different cities is an example of a simple graph.
The graph Gis non-trivial if it contains at least one edge, i.e., E 6= ;. non-trivial Equivalently, Gis non-trivial if Gis not an empty graph. The order of G, denoted by jGj, is the number of vertices of G, i.e., jGj= jVj. order, jGj The size of G, denoted by kGk, is the number of edges of G, i.e., kGk= jEj. size, kGk

Definition. A graph G is bipartite if it is the trivial graph or if its vertex set can be partitioned into two independent, non-empty sets A and B. We refer to { A, B } as a bipartiton of V(G). Note: Some people require a bipartite graph to be non-trivial. Examples include any even cycle, any tree, and the graph below.

Any other factor, if exists, is called non-trivial factor of N. Narcsh has plotted a graph of some constraints (linear inequations) with points A (0, 50), B (20 40), C (50, 100), D (O, 200) and E (IOO, 0). This graph is constructed using three non-trivial constraints and two trivial constraints. One of the non-trivial constraints is x + 2y ≥100.
Feb 18, 2022 · If G G contains vertices v,v′ v, v ′ and edge e = {v,v′}, e = {v, v ′}, then v, e,v′, e, v v, e, v ′, e, v is a nontrivial cycle which is not proper. Example 16.2.1 16.2. 1: A forest of trees. The graph in Figure 16.2.1 16.2. 1 is acyclic. Each of its connected components is a tree.
