Distance-regular Cayley graphs with least eigenvalue $- 2$

Alireza Abdollahi, Edwin van Dam, Mojtaba Jazaeri

We classify the distance-regular Cayley graphs with least eigenvalue $- 2$ and diameter at most three. Besides sporadic examples, these comprise of the lattice graphs, certain trian…

Directed strongly walk-regular graphs

Edwin R. van Dam, Gholamreza Omidi

We generalize the concept of strong walk-regularity to directed graphs. We call a digraph strongly $ℓ$ -walk-regular with $ℓ > 1$ if the number of walks of length $ℓ$ from a…
