Center node: "graph layouts via layered separators"
  Abstract: A k-queue layout of a graph consists of a total order of the vertices, and a partition of the edges into k sets such that no two edges that are in the same set are nested with respect to the vertex ordering. A k-track layout of a graph consists of a vertex k-colouring, and a total order of each vertex colour class, such that between each pair of colour classes no two edges cross. The queue-number (track-number) of a graph G, is the minimum k such that G has a k-queue (k-track) layout. #R##N#This paper proves that every n-vertex planar graph has track number and queue number at most O(log n). This improves the result of Di Battista, Frati and Pach [Foundations of Computer Science, (FOCS '10), pp. 365--374] who proved the first sub-polynomial bounds on the queue number and track number of planar graphs. Specifically, they obtained O(log^2 n) queue number and O(log^8 n) track number bounds for planar graphs. #R##N#The result also implies that every planar graph has a 3D crossing-free grid drawing in O(n log n) volume. The proof uses a non-standard type of graph separators.
