  SUMMARY = {Rough sets, developed by Pawlak, are important tool to
  describe situation of incomplete or partially unknown information.
  In this article we give the formal characterization of
  complementary
  rough inclusion functions,
  following a paper by Gomoli{\'n}ska. We use Jaccard index, Steinhaus
  generate metric, and introduce Marczewski-Steinhaus metric space.}}
