%0 Journal Article %T Strongly Regular Graphs From Unions of Cyclotomic Classes %A Tao Feng %A Qing Xiang %J Mathematics %D 2010 %I arXiv %X 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. %U http://arxiv.org/abs/1010.4107v3
