Spectra of graphs
TL;DR: This book gives an elementary treatment of the basic material about graph Spectra, both for ordinary, and Laplace and Seidel spectra, by covering standard topics before presenting some new material on trees, strongly regular graphs, two-graphs, association schemes, p-ranks of configurations and similar topics.

A "missing" family of classical orthogonal polynomials
Luc Vinet,Alexei Zhedanov +1 more
TL;DR: In this article, a family of orthogonal polynomials which satisfy (apart from a 3-term recurrence relation) an eigenvalue problem with a differential operator of Dunkl-type was studied.

The Subconstituent Algebra of an Association Scheme, (Part I)
TL;DR: In this article, the authors introduce a non-commutative, associative, semi-simple C-algebra T e T(x) whose structure reflects the combinatorial structure of Y.
