A construction for infinite families of semisymmetric graphs revealing their full automorphism group
Philippe Cara, Sara Rottey, Geertrui Van de Voorde
We give a general construction leading to different non-isomorphic families $Γ_{n,q}(\K)$ of connected -regular semisymmetric graphs of order embedded in $\PG(n+1,q)$…
A small minimal blocking set in PG(n,p^t), spanning a (t-1)-space, is linear
Peter Sziklai, Geertrui Van de Voorde
In this paper, we show that a small minimal blocking set with exponent e in PG(n,p^t), p prime, spanning a (t/e-1)-dimensional space, is an F_p^e-linear set, provided that p>5(t/e)…
Partial covers of PG(n,q)
Stefan Dodunekov, Leo Storme, Geertrui Van de Voorde
In this paper, we show that a set of q+a hyperplanes, q>13, a<(q-10)/4, that does not cover PG(n,q), does not cover at least q^(n-1)-aq^(n-2) points, and show that this lower bound…
The isomorphism problem for linear representations and their graphs
Philippe Cara, Sara Rottey, Geertrui Van de Voorde
In this paper, we study the isomorphism problem for linear representations. A linear representation Tn*(K) of a point set K is a point-line geometry, embedded in a projective space…
