Skew Hadamard difference sets from cyclotomic strongly regular graphs

Published 9 Jul 2012 in math.CO | (1207.2197v3)

Abstract: We find new constructions of infinite families of skew Hadamard difference sets in elementary abelian groups under the assumption of the existence of cyclotomic strongly regular graphs. Our construction is based on choosing cyclotomic classes in finite fields.
