Paul-Hermann ZieschangThe text provides a direct path from elementary algebraic and combinatorial observations to research problems.The book is the first attempt to systematically develop a structure theory of hypergroups

Closed Subsets,Notice that a closed subset . of a hypergroup . is a hypergroup with respect to the hyperoperation which one obtains from the hyperoperation on . if one restricts the domain of the hyperoperation on . to . and the codomain of this hyperoperation to the power set of ..

Tight Hypergroups,in. This provides us with a useful invariant which can be associated to each finite tight hypergroups, its residual depth, and it is this invariant which determines our study of finite tight hypergroups.

Involutions,oretic involutions.1 So it should come as no surprise that involutions play a similarly important role in the theory of hypergroups as group theoretic involutions do in group theory.We will see this on several occasions throughout the rest of this monograph.
