On the (non-)existence of tight distance-regular graphs: a local approach

Jack H. Koolen, Jae-Ho Lee, Shuang-Dong Li +3

Let $Γ$ denote a distance-regular graph with diameter $D \geq 3$ . Jurišić and Vidali conjectured that if $Γ$ is tight with classical parameters $(D, b, α, β)$ , $b \geq 2$ , then $Γ$ is n…

Non-geometric distance-regular graphs of diameter at least $3$ with smallest eigenvalue at least $- 3$

Jack Koolen, Kefan Yu, Xiaoye Liang +2

In this paper, we classify non-geometric distance-regular graphs of diameter at least $3$ with smallest eigenvalue at least $- 3$ . This is progress towards what is hoped to be an ev…
