The Nine Dragon Tree Conjecture for bounded forest decompositions
The Nine Dragon Tree Conjecture for bounded forest decompositions
Let be a graph, and let be nonnegative integers. The Nine Dragon Tree Conjecture. If
then decomposes into forests, one of which is -bounded. The conjecture is the graph-theoretic Nine Dragon Tree statement concerning decomposition into forests with one bounded component. It was proved by Jiang and Yang, so the conjecture is resolved.
