Blocking sets of almost Redei type

[摘要] We study minimal blocking sets in PG(2, q) having q + m points outside some fixed line. If 0 < m < (root q)/2 then either the blocking set is large, or every line contains 1 mod p points of the blocking set, where p is the characteristic of the field GF(q). (C) 1997 Academic Press.
