Pairwise balanced designs from finite fields
The author presents a general construction for \((q,K,\lambda)\) difference families over finite fields where sizes of the base blocks are in \(K\). Difference families generated by two or more initial base blocks are considered and these give rise to pairwise balanced designs (balanced block designs when \(|K|= 1\)). Examples of new difference families are presented.
