Abstract

Some approaches to the entropy of coverings, generalizing the case of the partition entropy, and some definitions of orderings and quasi–orderings of coverings as extensions to the covering context of various formulations of the standard order on partitions. Unfortunately, we here show that the problem of anti–monotonicity of non–pointwise entropy of coverings is still open. On the other side, we will illustrate an approach to generate a partition from a covering; we will then show how we can indirectly compare the entropies of two coverings, that are in a certain order relation, by comparing the entropies of the induced partitions.
