KnowraTree (graph theory)Linked fromLinked fromThe 17 pages that link to Tree (graph theory), each with the reason it gives.All 17Broader topic 6Related 5Narrower topic 5Compared with 1Graph (discrete mathematics)Broader topic: Trees are the simplest connected structures, with a unique path between each vertex pair.Undirected graphBroader topic: Trees are undirected graphs whose unique paths make them useful structural models.Handshaking lemmaBroader topic: A tree with n vertices has n−1 edges, so its degrees sum to 2n−2.Hosoya indexBroader topic: Removing a leaf yields a compact recurrence for the total matching count.Bunkbed conjectureBroader topic: Bunkbed inequalities can be analyzed particularly directly when the base graph is a tree.Burr–Erdős conjectureBroader topic: Trees are 1-degenerate, providing a basic family covered by the conjecture.
