Diameter and Radius of Graphs | Graph Theory
We define the radius of a graph and the diameter of a graph using the eccentricity of vertices. We relate these terms intuitively back to circles and discuss several examples of graph diameter and graph radius. We also introduce a theorem stating the diameter of a graph is bounded between

Graph Theory: 52. Radius and Diameter Examples
We have discussed the terms radius and diameter in a previous video. Here we work through two simple proofs which involve these concepts. First we show that the complement of a disconnected graph has diameter at most 2. Then we show that any given graph is the centre of some connected g

Graph Diameter is Bounded by Radius | Graph Theory
We prove the diameter of a graph lies between the radius and two times the radius of the graph. This is a fun result which invokes some of the feeling of the classic d=2r formula from elementary geometry, and all it takes to prove is the triangle inequality! #graphtheory Graphs are Metri

Diameter and Radius of Tree Graphs | Graph Theory
We discuss what family of tree graphs have maximum diameter, minimum diameter, maximum radius, and minimum radius. Recall the diameter of a graph is the maximum distance between any two vertices. The radius of a graph is the minimum eccentricity of any vertex. We'll find the star graphs ha

Graph Theory: 51. Eccentricity, Radius & Diameter
Eccentricity, radius and diameter are terms that are used often in graph theory. They are related to the concept of the distance between vertices. The distance between a pair of vertices is the length of a shortest path between them. We begin by reviewing some of the properties of dista

Diameter of a Graph | Graph Theory
What is the diameter of a graph in graph theory? This is a simple term we will define with examples in today's video graph theory lesson! Remember that the distance between two connected vertices in a graph is the length of a shortest path between those vertices. Here's my lesson on dist

Circle Terminology - Radius Diameter Sector Segment Chord Arc Tangent | Geometry | Math | FuseSchool
DESCRIPTION: There are some key words we need to know for circles: radius, circumference, diameter, sector, segment, tangent, chord and arc. In this video we discover what they all mean. The radius is the distance from the centre of a circle to a point on the circle. A diameter is the dist

Omer Bobrowski: Random Simplicial Complexes, Lecture III
A simplicial complex is a collection of vertices, edges, triangles, tetrahedra and higher dimensional simplexes glued together. In other words, it is a higher-dimensional generalization of a graph. In recent years there has been a growing effort in developing the theory of random simplicia
