On electric resistances for distance-regular graphs
Jack Koolen, Greg Markowsky, Jongyook Park
We investigate the behavior of electric potentials on distance-regular graphs, and extend some results of a prior paper. Our main result, Theorem 4, shows(together with Corollary 3…

There are only finitely many distance-regular graphs with valency k at least three, fixed ratio k2/k and large diameter
Jongyook Park, Jack H. Koolen, Greg Markowsky
In this paper, we show that for given positive integer C, there are only finitely many distance-regular graphs with valency k at least three, diameter D at least six and k2/k<=C. T…

Shilla distance-regular graphs
Jack H. Koolen, Jongyook Park
A Shilla distance-regular graph G (say with valency k) is a distance-regular graph with diameter 3 such that its second largest eigenvalue equals to a3. We will show that a3 divide…
