The Subconstituent Algebra of an Association Scheme (Part II)

چکیده
Abstract. This is a continuation of an article from the previous issue. In this section, we determine the structure of a thin, irreducible module for the Subconstituent algebra of a Pand Qpolynomial association scheme. Such a module is naturally associated with a Leonard system. The isomorphism class of the module is determined by this Leonard system, which in turn is determined by four parameters: the endpoint, the dual endpoint, the diameter, and an additional parameter /. If the module has sufficiently large dimension, the parameter / takes one of a certain set of values indexed by a bounded integer parameter e.

The Subconstituent Algebra of an Association Scheme, (Part I)
We introduce a method for studying commutative association schemes with "many" vanishing intersection numbers and/or Krein parameters, and apply the method to the Pand Qpolynomial schemes. Let Y denote any commutative association scheme, and fix any vertex x of Y. We introduce a non-commutative, associative, semi-simple C-algebra T = T(x) whose structure reflects the combinatorial structure of ...
متن کاملDistance-regular graphs of q-Racah type and the q-tetrahedron algebra
In this paper we discuss a relationship between the following two algebras: (i) the subconstituent algebra T of a distance-regular graph that has q-Racah type; (ii) the q-tetrahedron algebra ⊠q which is a q-deformation of the three-point sl2 loop algebra. Assuming that every irreducible T -module is thin, we display an algebra homomorphism from ⊠q into T and show that T is generated by the imag...
متن کاملTerwilliger Algebras of Wreath Powers of One-Class Association Schemes
In this paper, we study the subconstituent algebras, also called as Terwilliger algebras, of association schemes that are obtained as the wreath product of one-class association schemes Kn = H(1, n) for n ≥ 2. We find that the d-class association scheme Kn1 o Kn2 o · · · o Knd formed by taking the wreath product of Kni has the triple-regularity property. We determine the dimension of the Terwil...
متن کاملInheritance of hyper-duality in imprimitive Bose-Mesner algebras
We prove the following result concerning the inheritance of hyper-duality by block and quotient Bose-Mesner algebras associated with a hyper-dual pair of imprimitive Bose-Mesner algebras. Let M and M̃ denote Bose-Mesner algebras. Suppose there is a hyper-duality ψ from the subconstituent algebra of M with respect to p to the subconstituent algebra of M̃ with respect to p̃. Also suppose thatM is im...
متن کاملDually quasi-De Morgan Stone semi-Heyting algebras I. Regularity
This paper is the first of a two part series. In this paper, we first prove that the variety of dually quasi-De Morgan Stone semi-Heyting algebras of level 1 satisfies the strongly blended $lor$-De Morgan law introduced in cite{Sa12}. Then, using this result and the results of cite{Sa12}, we prove our main result which gives an explicit description of simple algebras(=subdirectly irreducibles) ...
