https://en.wikipedia.org/wiki/Blossom_tree_(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.

https://commons.wikimedia.org/wiki/Category:Tree_(graph_theory)Category:Tree (graph theory) A tree in mathematics and graph theory is an undirected graph in which any two vertices are connected by exactly one simple path. In other words, any connected graph without simple cycles is a tree. A forest is a disjoint union of trees.

Degeneracy (graph theory) - Wikipedia
https://en.wikipedia.org/wiki/Degeneracy_(graph_theory)In graph theory, a k-degenerate graph is an undirected graph in which every subgraph has a vertex of degree at most k: that is, some vertex in the subgraph touches k or fewer of the subgraph's edges. The degeneracy of a graph is the smallest value of …
Kruskal's tree theorem - Wikipedia
https://en.wikipedia.org/wiki/Kruskal's_tree_theoremKruskal's tree theorem. In mathematics, Kruskal's tree theorem states that the set of finite trees over a well-quasi-ordered set of labels is itself well-quasi-ordered under homeomorphic embedding. The theorem was conjectured by Andrew Vázsonyi and proved by Joseph Kruskal ( 1960 ); a short proof was given by Crispin Nash-Williams ( 1963 ).
