On well-quasi-ordering infinite trees – Nash–Williams's theorem revisited
Published online by Cambridge University Press: 18 May 2001
Abstract
Nash–Williams proved that the infinite trees are well-quasi-ordered (indeed, better-quasi-ordered) under the topological minor relation. We combine ideas of several authors into a more accessible and essentially self-contained short proof.
