If the answer is \"yes\" we say that $\\cP$ is compatible and $T$ displays $\\cP$. This decision problem is NP-complete even if all input trees are quartets, that is binary trees with exactly four leaves. In this paper, we prove a sufficient condition for a set of binary phylogenetic trees to be compatible. That result is used to give a short and self-contained proof of the known characterization of quartet sets of minimal cardinality which are displayed by a unique phylogenetic tree.", "revisions": [ { "version": "v1", "updated": "2010-06-28T07:58:50.000Z" } ], "analyses": { "keywords": [ "binary trees", "slim sets", "phylogenetic tree analysis", "binary phylogenetic trees", "unique phylogenetic tree" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1006.5280G" } } }
