Publications related to 'level k phylogenetic network' : N is called a level-k phylogenetic network if its subgraph induced on the vertices of any biconnected component of its underlying undirected graph U(N) contains at most k nodes with indegree 2 (i.e. any non-tree-like part of the network has at most k hybrid nodes). A level-1 phylogenetic network is also called a galled tree. A short overview of results and open problems on this topic was compiled here by Leo van Iersel.
