Directed Acyclic Outerplanar Graphs Have Constant Stack Number
Paul Jungeblut, Laura Merker, Torsten Ueckerdt
The stack number of a directed acyclic graph is the minimum for which there is a topological ordering of and a -coloring of the edges such that no two edges of the s…

The product structure of squaregraphs
Robert Hickingbotham, Paul Jungeblut, Laura Merker +1
A squaregraph is a plane graph in which each internal face is a -cycle and each internal vertex has degree at least 4. This paper proves that every squaregraph is isomorphic to…

Three-dimensional graph products with unbounded stack-number
David Eppstein, Robert Hickingbotham, Laura Merker +3
We prove that the stack-number of the strong product of three -vertex paths is . The best previously known upper bound was . No non-trivial lower bound was kno…
