On the size of a blocking set in PG(2,p)

Research output: Contribution to journalArticleAcademicpeer-review


We show that the size of a non-trivial blocking set in the Desarguesian projective planePG(2,p), wherep is prime, is at least 3(p+1)/2. This settles a 25 year old conjecture of J. di Paola.
