Graph families | Regular graphs | Algebraic graph theory
In discrete mathematics, a walk-regular graph is a simple graph where the number of closed walks of any length from a vertex to itself does not depend on the choice of vertex. (Wikipedia).
What is a Walk? | Graph Theory
What is a walk in the context of graph theory? That is the subject of today's math lesson! A walk in a graph G can be thought of as a way of moving through G, where you start at any vertex in the graph, and then move to other vertices through the edges in the graph. In a walk, you are allo

What is a Path Graph? | Graph Theory
What is a path graph? We have previously discussed paths as being ways of moving through graphs without repeating vertices or edges, but today we can also talk about paths as being graphs themselves, and that is the topic of today's math lesson! A path graph is a graph whose vertices can

Graph Theory: 18. Every Walk Contains a Path
Here I show a proof that every walk in a graph contains a path. This is why we can define connected graphs as those graphs for which there is a path between every pair of vertices. --An introduction to Graph Theory by Dr. Sarada Herke. For quick videos about Math tips and useful facts, c

What is a Path? | Graph Theory
What is a path in the context of graph theory? We go over that in today's math lesson! We have discussed walks, trails, and even circuits, now it is about time we get to paths! Recall that a walk is a sequence of vertices in a graph, such that consecutive vertices are adjacent. A path is t

Proof: If There is a u-v Walk then there is a u-v Path | Every Walk Contains a Path, Graph Theory
PLEASE NOTE: The condition that u is not equal to v is not technically necessary, because the path described by the sequence ( u ) is considered a u-u path of length 0. If we allow this to be a path, the proof we go over covers this possibility with no changes necessary, and so the theorem

What are Regular Graphs? | Graph Theory
What is a regular graph? That is the subject of today's math lesson! A graph is regular if and only if every vertex in the graph has the same degree. If every vertex in a graph has degree r, then we say that graph is "r-regular" or "regular of degree r". If a graph is not regular, as in, i
