A linear (qd, q, t)-perfect hash family of size s in a vector space V of order qd over a field F of order q consists of a set S = {1, . . . , s} of linear functionals from V to F ...

In 1960 Hughes and Kleinfeld [4] constructed a finite semifield which is two dimensional over a weak nucleus. In 1965 Knuth [7] constructed a further three families of finite semif...

We define a mixed partition of = PG(d, qr) to be a partition of the points of into subspaces of two distinct types, for instance, a partition of PG(2n - 1, q2) into (n - 1)-spac...

Davis, Jedwab and Smith recently proved that there are no 2-dimensional Barker arrays except of size 2?2. We show that the existence of a (d+1)-dimensional Barker array implies th...

Many different divisible designs are already known. Some of them possess remarkable automorphism groups, so called dual translation groups. The existence of such an automorphism g...
