|Title:||FLOW IN PLANAR GRAPHS: A SURVEY OF RECENT RESULTS.
|Authors:||S. Khuller and J. Naor
We briefly review some of the recent results on flow in planar graphs. The older results in the area are reviewed somewhat more briefly. The main interest in planar flow was regenerated when it was observed in both [41,34] that the single source/sink edge capacity flow problem was not the ``basic'' problem that should be studied. This survey paper essentially reviews some of the techniques that were developed to capture more general versions of the planar flow problem. Some other interesting results related to planar flow problems are also reported.
