Skew Hadamard difference sets from cyclotomic strongly regular graphs
Koji Momihara
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 gr…

Evaluation of the weight distribution of a class of cyclic codes based on index 2 Gauss sums
Tao Feng, Koji Momihara
The duals of cyclic codes with two zeros have been extensively studied, and their weight distributions have recently been evaluated in some cases. In this note, we determine the we…

Strongly Regular Cayley Graphs, Skew Hadamard Difference Sets, and Rationality of Relative Gauss Sums
Koji Momihara
In this paper, we give constructions of strongly regular Cayley graphs and skew Hadamard difference sets. Both constructions are based on choosing cyclotomic classes in finite fiel…
