Stacks, Queues and Tracks: Layouts of Graph Subdivisions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2005 A \emphk-stack layout (respectively, \emphk-queuelayout) of a graph consists of a total order of the vertices, and a partition of the edges into k sets of non-crossing (non-nested) edges with respect to the vertex ordering.
