Abstract
For a hypergraph let denote the minimal number of edges from covering . An edge of is said to represent {\em fairly} (resp. {\em almost fairly}) a partition of if (resp. ) for all . In matroids any partition of can be represented fairly by some independent set. We look for classes of hypergraphs in which any partition of can be represented almost fairly by some edge. We show that this is true when is the set of independent sets in a path, and conjecture that it is true when is the set of matchings in . We prove that partitions of into three sets can be represented almost fairly. The methods of proofs are topological.
