Strongly Regular Graphs with Parameters (4m4, 2m4 + m2, m4 + m2, m4 + m2) Exist for All m>1 [PDF]

Using results on Hadamard difference sets, we construct regular graphical Hadamard matrices of negative type of order 4m4 for every positive integer m. If m > 1, such a Hadamard matrix is equivalent to a strongly regular graph with parameters (4m4, 2m4 ...

Graphs with Few Eigenvalues. An Interplay between Combinatorics and Algebra. [PDF]

: Two standard matrix representations of a graph are the adjacency matrix and the Laplace matrix. The eigenvalues of these matrices are interesting parameters of the graph.

Seidel-equivalence of strongly regular graphs

, 1968
Seidel-equivalence of two strongly regular graphs G and G∗ with the same parameters is defined. Necessary conditions for the existence of partially balanced incomplete block designs with L2(4) and pseudo-T(8) association schemes are also obtained.
