    • A bound for the maximum weight of a linear code 

      Ball, Simeon Michael; Blokhuis, Aart (2013-03-21)
      Article
      Accés obert
      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
      Accés obert
      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
      Accés obert
      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 ...
    • A polynomial-time reduction from the multi-graph isomorphism problem to additive codeequivalence 

      Ball, Simeon Michael; Dixon, James (2021-12-02)
      Article
      Accés obert
      We present a polynomial-time reduction from the multi-graph isomorphism problem to the problem of code equivalence of additive codes over finite extensions of the field with two elements.
    • Additive MDS codes 

      Ball, Simeon Michael; Adriaensen, Sam (2022)
      Text en actes de congrés
      Accés obert
      We prove that an additive code over a finite field which has a few projections which are equivalent to a linear code is itself equivalent to a linear code, providing the code is not too short.

    • Arcs and tensors 

      Ball, Simeon Michael; Lavrauw, Michel (2019-08-01)
      Article
      Accés obert
      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 ...
    • Arcs in finite projective spaces 

      Ball, Simeon Michael; Lavrauw, Michel (2019-11-23)
      Article
      Accés restringit per política de l'editorial
      This is an expository article detailing results concerning large arcs in finite projective spaces. It is not strictly a survey but attempts to cover the most relevant results on arcs, simplifying and unifying proofs of ...
