On the small weight codewords of the functional codes C_2(Q), Q a non-singular quadric (2009)
Edoukou, Frédéric, Hallez, Anja, Rodier, François, Storme, Leo
We study the small weight codewords of the functional code C_2(Q), with Q a non-singular quadric of PG(N,q). We prove that the small weight codewords correspond to the intersections of Q with the...

Generalised dual arcs and Veronesean surfaces, with applications to cryptography (2009)
Klein, Andreas, Schillewaert, Jeroen, Storme, Leo
We start by defining generalised dual arcs, the motivation for defining them comes from cryptography, since they can serve as a tool to construct authentication codes and secret sharing schemes. We...
Tight sets, weighted m-covers, weighted m-ovoids, and minihypers (2009)
De Beule, Jan, Patrick, Govaerts, Hallez, Anja, Storme, Leo
Minihypers are substructures of projective spaces introduced to study linear codes meeting the Griesmer bound. Recently, many results in finite geometry were obtained by applying characterization...
Small weight codewords in the LDPC codes arising from linear representations of geometries (2009)
Pepe, Valentina, Storme, Leo, Van De Voorde, Geertrui
In this article, we investigate the minimum distance and small weight codewords of the LDPC codes of linear representations, using only geometrical methods. First, we present a new lower hound on the...

Computing with the square root of NOT (2009)
De Vos, Alexis, De Beule, Jan, Storme, Leo
We add to the two classical reversible 1-bit logic gates, i.e. the identity gate (a.k.a. the follower) and the NOT gate (a.k.a. the inverter), an extra gate, i.e. the square root of NOT. Similarly,...

Partial ovoids and partial spreads in symplectic and orthogonal polar spaces (2008)
De Beule, Jan, Klein, Andreas, METSCH, K, Storme, Leo
We present improved lower bounds on the sizes of small maximal partial ovoids and small maximal partial spreads in the classical symplectic and orthogonal polar spaces, and improved upper bounds on...
Partial ovoids and partial spreads in finite classical polar spaces (2008)
De Beule, Jan, Klein, Andreas, Metsch, Klaus, Storme, Leo
We survey the main results on ovoids and spreads, large maximal partial ovoids and large maximal partial spreads, and on small maximal partial ovoids and small maximal partial spreads in classical...
On the code generated by the incidence matrix of points and k-spaces in PG(n, q) and its dual (2008)
Lavrauw, Michel, Storme, Leo, Van De Voorde, Geertrui
In this paper, we study the p-ary linear code C-k (n, q), q = p(h), p prime, h >= 1, generated by the incidence matrix of points and k-dimensional spaces in PG(n, q). For k >= n/2, we link codewords...
Tangency sets in PG(3,q) (2008)
A tangency set of PG(d, q) is a set Q of points with the property that every point P of Q lies on a hyperplane that meets Q only in P. It is known that a tangency set of PG(3, q) has at most q(2) + 1...
On the non-existence of a maximal partial spread of size 76 in PG(3,9) (2008)
Heden, Olof, Marcugini, Stefano, Pambianco, Fernanda, Storme, Leo
We prove the non-existence of maximal partial spreads of size 76 in PG(3,9). Relying on the classification of the minimal blocking sets of size 15 in PG(2, 9) [22], we show that there are only two...
Minimal blocking sets in PG(2,9) (2008)
Pambianco, Fernanda, Storme, Leo
We classify the minimal blocking sets of size 15 in PG(2,9). We show that the only examples are the projective triangle and the sporadic example arising from the secants to the unique complete 6-arc...
