Pseudo-distance-regularized graphs are distance-regular or distance-biregular
Linear Algebra and its Applications, 2012 The concept of pseudo-distance-regularity around a vertex of a graph is a natural generalization, for non-regular graphs, of the standard distance-regularity around a vertex. In this note, we prove that a pseudo-distance-regular graph around each of its vertices is either distance-regular or distance-biregular.

On the center of distances [PDF]
European Journal of Mathematics, 2017 In this paper we introduce the notion of the center of distances of a metric space, which is required for a generalization of the theorem by J. von Neumann about permutations of two sequences with the same set of cluster points in a compact metric space.

Distance-regularised graphs are distance-regular or distance-biregular
Journal of Combinatorial Theory, Series B, 1987 AbstractOne problem with the theory of distance-regular graphs is that it does not apply directly to the graphs of generalised polygons. In this paper we overcome this difficulty by introducing the class of distance-regularised graphs, a natural common generalisation.
