Solution to Bishnoi's conjecture on minimal t-fold blocking sets of maximal size

Combinatorics 2017-05-11 v1

Abstract

Bishnoi conjectured that if a minimal t-fold blocking set in a projective plane of prime power order has maximal size then it is either a projective plane minus one point, the complement of a Baer subplane or a unital. In this note we prove this conjecture.
