A Spectral Equivalent Condition of the Tex-Polynomial Property for Association Schemes
Hirotake Kurihara, Hiroshi Nozaki
The Electronic Journal of Combinatorics   21(3) 1-8   2014   [Refereed]
Hirotake KURIHARA
Annals of Combinatorics      2013   [Refereed]
The set of subspaces of a given dimension in an attenuated space has a structure of a symmetric association scheme and this association scheme is called an association scheme based on an attenuated space. Association schemes based on attenuated sp...

Designs, Codes and Cryptography   65(1) 89-98   2012   [Refereed]
We give an excess theorem for spherical 2-designs. This theorem is a dual version of the spectral excess theorem for graphs, which gives a characterization of distance-regular graphs, among regular graphs in terms of the eigenvalues and the excess...

Journal of Combinatorial Theory, Series A   119(1) 57-62   2012   [Refereed]
We prove a necessary and sufficient condition for a symmetric association scheme to be a Tex-polynomial scheme.

Advances in Geometry   11(2) 293-301   2011   [Refereed]
An Tex-flat association scheme, denoted Tex, is defined on the set of affine Tex-flats, the cosets of an Tex-dimensional subspace of an Tex-dimensional vector space over the finite field Tex. This association scheme w...

The aim of this paper is a characterization of great antipodal sets of
complex Grassmannian manifolds as certain designs with the smallest
cardinalities.
