On standard two-intersection sets in PG(rq)

  • Fulvio Zuanni


In this paper, we extend and analyze in a finite projective space of any dimension the notion of standard two-intersection sets previously introduced in the projective plane by Penttila and Royle (Des Codes Cryptogr 6:229–245, 1995), see also Blokhuis and Lavrauw (J Combin Theory Ser A 99:377–382, 2002). Moreover, given a pair of suitable distinct standard two-intersection sets in a finite projective space it is possible to get further standard two-intersection sets by applying elementary set-theoretical operations to the elements of the pair.
