Avoiding secants of given size in finite projective planes
Tamás Héger, Zoltán Lóránt Nagy
Let be a prime power and be a natural number. What are the possible cardinalities of point sets in a projective plane of order , which do not intersect any line at…

Dominating sets in projective planes
Tamás Héger, Zoltán Lóránt Nagy
We describe small dominating sets of the incidence graphs of finite projective planes by establishing a stability result which shows that dominating sets are strongly related to bl…
