Construction of Directed Strongly Regular Graphs Using Block Matrices
Francis Adams, Alexandra Gendreau, Oktay Olmez +1
The concept of directed strongly regular graphs was introduced by Duval in his paper, A Directed Graph Version of Strongly Regular Graphs. Duval also provided several construction…
