    • A bound for the maximum weight of a linear code 

      Ball, Simeon Michael; Blokhuis, Aart (2013-03-21)
      Article
      Open Access
      It is shown that the parameters of a linear code over Fq of length n, dimension k, minimum weight d, and maximum weight m satisfy a certain congruence relation. In the case that q = p is a prime, this leads to the bound m ...
    • A finite version of the Kakeya problem 

      Ball, Simeon Michael; Blokhuis, Aart; Domenzain, Diego (2016-06-02)
      Article
      Open Access
      Let L be a set of lines of an affine space over a field and let S be a set of points with the property that every line of L is incident with at least N points of S. Let D be the set of directions of the lines of L considered ...
    • A generalisation of Sylvester's problem to higher dimensions 

      Ball, Simeon Michael; Monserrat, Joaquim (2017-07-01)
      Article
      Open Access
      In this article we consider $S$ to be a set of points in $d$-space with the property that any $d$ points of $S$ span a hyperplane and not all the points of $S$ are contained in a hyperplane. The aim of this article is to ...

      Ball, Simeon Michael; Lavrauw, Michel (2019-08-01)
      Article
      Open Access
      To an arc A of PG(k-1,q) of size q+k-1-t we associate a tensor in ¿¿k,t(A)¿¿k-1 , where ¿k,t denotes the Veronese map of degree t defined on PG(k-1,q) . As a corollary we prove that for each arc A in PG(k-1,q) of size ...
