Graph theory objects | Planar graphs | Trees (graph theory)
In the study of planar graphs, blossom trees are trees with additional directed half edges. Each blossom tree is associated with an embedding of a planar graph. Blossom trees can be used to sample random planar graphs. (Wikipedia).
Graph Theory: 36. Definition of a Tree
In this video I define a tree and a forest in graph theory. I discuss the difference between labelled trees and non-isomorphic trees. I also show why every tree must have at least two leaves. An introduction to Graph Theory by Dr. Sarada Herke. Related Videos: http://youtu.be/zxu0dL436gI

Graph Theory: 38. Three ways to Identify Trees
A proof that a graph of order n is a tree if and only if it is connected and has n-1 edges. This, together with the previous video and the definition of a tree, gives three ways to determine if a graph is a tree. An introduction to Graph Theory by Dr. Sarada Herke. Related Videos: http:/

Intro to Tree Graphs | Trees in Graph Theory, Equivalent Definitions
What are trees in graph theory? Tree graphs are connected graphs with no cycles. We'll introduce them and some equivalent definitions, with of course examples of tree graphs in today's graph theory video lesson! Some equivalent definitions of tree graphs are as follows. A graph is a tree
