Dominating sets in projective planes (with Zoltán Lóránt Nagy). To appear in

Blocking and Double Blocking Sets in Finite Planes (with J. De Beule, T.~Szônyi, G. Van de Voorde).

Semiarcs with a long secant in PG(2,q) (with B. Csajbók and Gy. Kiss).

Search problems in vector spaces (with B. Patkós and M. Takáts).

Some graph theoretic aspects of finite geometries. PhD Thesis (2013). Pdf

Resolving sets and semi-resolving sets in finite projective planes (with M. Takáts).

The 2-blocking number and the upper chromatic number of PG(2,q) (with G. Bacsó and T. Szônyi).

The Zarankiewicz problem, cages, and geometries (with G. Damásdi and T. Szônyi).

NOTE: The correct value of Z_{2,2}(15,15) is 61 as reported by Brendan Mckay in June, 2015. In this article we used 60 instead as published by Richard K. Guy.

Three more errors in Guy's (and hence in our) table was reported by Andrew Kay (April 2016), as follows: Z_{2,2}(14,26)=82; Z_{2,2}(14,27)=84; Z_{2,2}(14,28)=86. Andrew Kay maintains an online database for Zarankiewicz numbers.

On (k,6) graphs arising from projective planes (with A. Gács and Zs. Weiner),

Finding small regular graphs of girth 6, 8, and 12 as subgraphs of cages (with G. Araujo-Pardo, C. Balbuena),

Permutations, hyperplanes and polynomials over finite fields (with A. Gács, L. Z. Nagy and D. Pálvölgyi),

On geometric constructions of (k,g)-graphs (with A. Gács),
