Landau set

In voting systems, the Landau set (or uncovered set, or Fishburn set) is the set of candidates such that for every other candidate , there is some candidate (possibly the same as or ) such that is not preferred to and is not preferred to . In notation, is in the Landau set if , , .

The Landau set is a nonempty subset of the Smith set. It was discovered by Nicholas Miller.
