Distance-Biregular Graphs and Orthogonal Polynomials
(University of Waterloo, 2023-09-15)This thesis is about distance-biregular graphs– when they exist, what algebraic and structural properties they have, and how they arise in extremal problems. We develop a set of necessary conditions for a distance-biregular ...
