»ã±¨ÌáÒª£ºWe will determine all the distance-regular graphs with three distinct distance eigenvalues when one of them is

equal to 0. Then we will discuss distance-regular graphs with three distinct distance eigenvalues with diameter three.

This is based on ongoing work with Brhane Gebremichel, Mamoon Abdullah and Sakander Hayat.
