Strongly walk-regular graphs [PDF]
We study a generalization of strongly regular graphs. We call a graph strongly walk-regular if there is an $\ell >1$ such that the number of walks of length $\ell$ from a vertex to another vertex depends only on whether the two vertices are the same, adjacent, or not adjacent. We will show that a strongly walk-regular graph must be an empty graph, a

On strongly regular self ‐ complementary graphs
Journal of Graph Theory, 1981AbstractIt is shown that certain conditions assumed on a regular self‐complementary graph are not sufficient for the graph to be strongly regular, answering in the negative a question posed by Kotzig in [1].

A graph (simple, undirected, and loopless) of order v is called strongly regular with parameters v, k,λ,μ whenever it is not complete or edgeless.

Strongly regular vertices and partially strongly regular graphs.
Ars Comb., 2004Summary: A strongly regular vertex with parameters \((\lambda,\mu)\) in a graph is a vertex \(x\) such that the number of neighbors any other vertex \(y\) has in common with \(x\) is \(\lambda\) if \(y\) is adjacent to \(x\), and is \(\mu\) if \(y\) is not adjacent to \(x\).

On the (99,14,1,2) strongly regular graph
1984The existence of a strongly regular graph with parameters as in the title is still in doubt. It is proved that there is no such graph with an automorphism of order 11, and the only primes which could divide the order of the automorphism group of such a graph are 2, 3, 5 and 7.
