We consider ferromagnetic Ising models on graphs that converge locally to trees. Examples include random regular graphs with bounded degree and uniformly random graphs with bounded average degree. We ...

The number comes from a simple game of trees—meaning the charts used in graph theory. In this game, you make a forest of trees using seeds.

The Yule tree graph The Yule tree is a graph with one edge coming in and two edges coming out of each branch-point. The branches represent the time periods between the evolution of new species. If the ...
