Abstract
We characterize the minimum size blocking sets with respect to the external lines to a non-singular quadric or a quadric with a point vertex in PG(), and . Our results show that these minimum size blocking sets are equal to the sets of points not on the quadric in a suitably chosen hyperplane with respect to the quadric.
