Strongly Regular Graphs From Unions of Cyclotomic Classes

arXiv:1010.4107

Abstract

We give two constructions of strongly regular Cayley graphs on finite fields $\F_q$ by using union of cyclotomic classes and index 2 Gauss sums. In particular, we obtain twelve infinite families of strongly regular graphs with new parameters.
