Powers of Gauss sums in quadratic fields
Koji Momihara
In the past two decades, many researchers have studied {\it index } Gauss sums, where the group generated by the characteristic of the underling finite field is of index …
Pure Gauss sums and skew Hadamard difference sets
Koji Momihara
Chowla~(1962), McEliece~(1974), Evans~(1977, 1981) and Aoki~(1997, 2004, 2012) studied Gauss sums, some integral powers of which are in the field of rational numbers. Such Gauss su…
Cameron-Liebler Line Classes with parameter
Tao Feng, Koji Momihara, Morgan Rodgers +2
Cameron-Liebler line classes were introduced in \cite{CL}, and motivated by a question about orbits of collineation groups of $\PG(3,q)$. These line classes have appeared in differ…
New constructions of strongly regular Cayley graphs on abelian groups
Koji Momihara
Davis and Jedwab (1997) established a great construction theory unifying many previously known constructions of difference sets, relative difference sets and divisible difference s…
