Amorphic association schemes with negative Latin square type graphs

James A. Davis, Qing Xiang

Applying results from partial difference sets, quadratic forms, and recent results of Brouwer and Van Dam, we construct the first known amorphic association scheme with negative La…

Negative Latin square type partial difference sets in nonelementary abelian 2-groups

James A. Davis, Qing Xiang

Combining results on quadrics in projective geometries with an algebraic interplay between finite fields and Galois rings, we construct the first known family of partial difference…
