Group rings and character sums: tricks of the trade
Jonathan Jedwab, Shuxing Li
The combination of the group ring setting with the methods of character theory allows an elegant and powerful analysis of various combinatorial structures, via their character sums…
Sets of mutually orthogoval projective and affine planes
Charles J. Colbourn, Colin Ingalls, Jonathan Jedwab +3
A pair of planes, both projective or both affine, of the same order and on the same pointset are orthogoval if each line of one plane intersects each line of the other plane in at…
Constructions and restrictions for balanced splittable Hadamard matrices
Jonathan Jedwab, Shuxing Li, Samuel Simon
A Hadamard matrix is balanced splittable if some subset of its rows has the property that the dot product of every two distinct columns takes at most two values. This definition wa…
A group-based structure for perfect sequence covering arrays
Jingzhou Na, Jonathan Jedwab, Shuxing Li
An -perfect sequence covering array with multiplicity , denoted PSCA, is a multiset whose elements are permutations of the sequence and which c…
Packings of partial difference sets
Jonathan Jedwab, Shuxing Li
A packing of partial difference sets is a collection of disjoint partial difference sets in a finite group . This configuration has received considerable attention in design the…
Constructions of difference sets in nonabelian 2-groups
Taylor Applebaum, John Clikeman, James A. Davis +5
Difference sets have been studied for more than 80 years. Techniques from algebraic number theory, group theory, finite geometry, and digital communications engineering have been u…
