Abstract

Some quasi---ordering for coverings are here defined. Different definitions of entropies and co---entropies for coveringsare examined, also focusing on the distinction between the here called globaland pointwiseapproaches to co---entropies. The entropies and co---entropies are defined both for coverings generated from an information system via a similarity relation and for generic coverings of a universe X(i.e., coverings not necessarily generated from an information system via a similarity relation). The behavior of the entropies and co---entropies for coverings with respect to the defined quasi---orderings is thus explored.
