Generalized wreath products of association schemes
نویسنده
چکیده
Given a finite partially ordered set X, and, for each x in X, an association scheme on a set Ωx, we show how to define an association scheme on ∏ x Ωx in a way that specializes to iterated crossing and nesting when X is seriesparallel. The character table of the new association scheme is found.

On generalized semidirect product of association schemes
In this paper, we introduce a new product operation of association schemes in order to generalize the notion of semidirect products and wreath product. We then show that our construction covers some association schemes which are neither wreath products nor semidirect products of two given association schemes.

متن کاملSemidirect Products of Association Schemes
In his 1996 work developing the theory of association schemes as a ‘generalized’ group theory, Zieschang introduced the concept of the semidirect product as a possible product operation of certain association schemes. In this paper we extend the semidirect product operation into the entire set of association schemes. We then derive a way to decompose certain association schemes into smaller ass...
متن کاملTerwilliger algebras of wreath products of one-class association schemes
In this paper, we study the wreath product of one-class association schemes Kn =H(1, n) for n≥ 2. We show that the d-class association scheme Kn1 Kn2 · · · Knd formed by taking the wreath product of Kni (for ni ≥ 2) has the triple-regularity property. Then based on this fact, we determine the structure of the Terwilliger algebra of Kn1 Kn2 · · · Knd by studying its irreducible modules. In parti...
متن کاملCrested Products of Association Schemes
In this paper, we define a new type of product of association schemes (and of the related objects, permutation groups and orthogonal block structures), which generalizes the direct and wreath products (which are referred to as “crossing” and “nesting” in the statistical literature.) Given two association schemes Qr for r = 1, 2, each having an inherent partition Fr (that is, a partition whose e...
