Abstract
The purpose of this paper is to investigate extension problems for the category of finite commutative hypergroups. In fact, sufficiently many extensions will be provided by applying the notion of a field of finite commutative hypergroups. Moreover, the duality of such extensions will be studied via fields of finite commutative hypergroups.
