[HTML][HTML] Stability of k mod p multisets and small weight codewords of the code generated by the lines of PG (2, q)

T Szőnyi, Z Weiner - Journal of Combinatorial Theory, Series A, 2018 - Elsevier
In this paper, we prove a stability result on k mod p multisets of points in PG (2, q), q= p h.
The particular case k= 0 is used to describe small weight codewords of the code generated …

Lengths of divisible codes: the missing cases

S Kurz - Designs, Codes and Cryptography, 2024 - Springer
A linear code C over\({\mathbb {F}} _q\) is called\(\Delta\)-divisible if the Hamming
weights\({\text {wt}}(c)\) of all codewords\(c\in C\) are divisible by\(\Delta\). The possible …

Avoiding secants of given size in finite projective planes

T Héger, ZL Nagy - Journal of Combinatorial Designs, 2024 - Wiley Online Library
Let qq be a prime power and kk be a natural number. What are the possible cardinalities of
point sets SS in a projective plane of order qq, which do not intersect any line at exactly kk …

Blocking sets of certain line sets related to a hyperbolic quadric in PG(3, q)

BK Sahoo, B Sahu - Advances in Geometry, 2019 - degruyter.com
For a fixed hyperbolic quadric 𝓗 in PG (3, q), let 𝔼 (respectively 𝕋, 𝕊) denote the set of all
lines of PG (3, q) which are external (respectively tangent, secant) with respect to 𝓗. We …

On bisecants of Rédei type blocking sets and applications

B Csajbók - Combinatorica, 2018 - Springer
If B is a minimal blocking set of size less than 3 (q+ 1)= 2 in PG (2, q), q is a power of the
prime p, then Szőnyi's result states that each line meets B in 1 (mod p) points. It follows that …

Semiarcs with a long secant in PG (2, q)

B Csajbók, T Héger, G Kiss - Innovations in Incidence Geometry: Algebraic …, 2015 - msp.org
A t-semiarc is a point set S t with the property that the number of tangent lines to S t at each
of its points is t. We show that if a small t-semiarc S t in PG (2, q) has a large collinear subset …

[PDF][PDF] Small stopping sets in finite projective planes of order q

V Napolitano - The Art of Discrete and Applied Mathematics, 2021 - scholar.archive.org
A configuration C in a (finite) incidence structure is a subset C of blocks. If every point on a
block of C belongs to at least one other block of C, then C is called stopping set (or …
