Distance-regular graphs

ER Van Dam, JH Koolen, H Tanaka - arxiv preprint arxiv:1410.6294, 2014 - arxiv.org
This is a survey of distance-regular graphs. We present an introduction to distance-regular
graphs for the reader who is unfamiliar with the subject, and then give an overview of some …

[HTML][HTML] On the number of irreducible modular representations of a P and Q polynomial scheme

O Shimabukuro - European Journal of Combinatorics, 2007 - Elsevier
Whereas results about the number of irreducible modular representations of finite groups
are known, those of Bose–Mesner algebras of association schemes are not well understood …

[HTML][HTML] On structures of modular adjacency algebras of Johnson schemes

O Shimabukuro - Discrete Mathematics, 2011 - Elsevier
In this paper, we consider algebras over a field of characteristic p, which are generated by
adjacency algebras of Johnson schemes. If the algebra is semisimple, the structure is the …

Representations of p′-valenced Schurian schemes

A Hanaki, Y Hieda - SUT Journal of Mathematics, 2008 - projecteuclid.org
Let p be a prime number. We consider representations of p′-valenced Schurian schemes
over a field of characteristic p, especially the case that the cardinality of the underlying set …
