Abstract: Semiovals which are contained in the union of three concurrent lines are studied. The notion of a strong semioval is introduced, and a complete classification of these objects in PG▫$(2,p)$▫ and PG▫$(2,p^2)$▫, ▫$p$▫ an odd prime, is given.Keywords: mathematics, semioval, group factorizationPublished in RUP: 15.10.2013; Views: 2843; Downloads: 130 Link to full text
