COMPLEMENTARY SPANNING TREES
Abstract
Given a network G whose arcs partition into non-overlapping 'clubs' (sets) R sub i, D. Ray Fulkerson has considered the problem of constructing a spanning tree such that no two of its arcs belong to (represent) the same club and has stated necessary and sufficient conditions for such trees to exist. When each club R sub i consists of exactly two arcs, we shall refer to each of the arc pair as the 'complement' of the other, and the representative tree as a complementary tree. Our objective is to prove the following theorem: If there exists one complementary tree, there exists at least two.
