Distance-regular graphs with classical parameters that support a uniform structure: case $q \geq 2$

Blas Fernández, Roghayeh Maleki, Štefko Miklavič +1

Let $Γ = (X, R)$ denote a finite, simple, connected, and undirected non-bipartite graph with vertex set $X$ and edge set $R$ . Fix a vertex $x \in X$ , and define $\…

Characterizing bipartite distance-regularized graphs with vertices of eccentricity 4

Blas Fernández, Marija Maksimović, Sanja Rukavina

The characterization of bipartite distance-regularized graphs, where some vertices have eccentricity less than four, in terms of the incidence structures of which they are incidenc…

Certain graphs with exactly one irreducible $T$ -module with endpoint $1$ , which is thin: the pseudo-distance-regularized case

Blas Fernández

Let $Γ$ denote a finite, simple and connected graph. Fix a vertex $x$ of $Γ$ which is not a leaf and let $T = T (x)$ denote the Terwilliger algebra of $Γ$ with respect to $x$ . Assume…
