The Connectivity of Strongly Regular Graphs

open access: yesEuropean Journal of Combinatorics, 1985
Es wird bewiesen, daß in einem streng regulären Graphen jede kleinste trennende Eckenmenge aus den Nachbarn einer Ecke bestehen muß.

The Extendability of Matchings in Strongly Regular Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2014
A graph $G$ of even order $v$ is called $t$-extendable if it contains a perfect matching, $t<v/2$ and any matching of $t$ edges is contained in some perfect matching. The extendability of $G$ is the maximum $t$ such that $G$ is $t$-extendable. In this paper, we study the extendability properties of strongly regular graphs.

Disconnecting strongly regular graphs

open access: yesEuropean Journal of Combinatorics, 2014
In this paper, we show that the minimum number of vertices whose removal disconnects a connected strongly regular graph into non-singleton components, equals the size of the neighborhood of an edge for many graphs. These include blocks graphs of Steiner $2$-designs, many Latin square graphs and strongly regular graphs whose intersection parameters are ...

On the Clique Number of a Strongly Regular Graph [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2018
We determine new upper bounds for the clique numbers of strongly regular graphs in terms of their parameters. These bounds improve on the Delsarte bound for infinitely many feasible parameter tuples for strongly regular graphs, including infinitely many parameter tuples that correspond to Paley graphs.

Strongly regular graphs with strongly regular decomposition

open access: yesLinear Algebra and its Applications, 1989
Partitions of strongly regular graphs into two strongly regular subgraphs are studied. Such partitions give rise to quasi-symmetric designs and other types of interesting configurations. Necessary conditions for the existence of such partitions are derived. Several constructions are given and a table of all feasible parameter sets up to 300 vertices is

Binary Codes of Strongly Regular Graphs [PDF]

open access: yesDesigns, Codes and Cryptography, 1999
The binary code of a graph is the linear code generated by the rows of the adjacency matrix of the graph. The authors investigate, with the exception of two parameter sets, the codes from known strongly regular graphs with fewer than 45 vertices. They also consider the codes obtained when the main diagonal of the adjacency matrix is the all-one vector.
