A note and a short survey on supporting lines of compact convex sets in the plane
Gábor Czédli, László L. Stachó
After surveying some known properties of compact convex sets in the plane, we give a two rigorous proofs of the general feeling that supporting lines can be slide-turned slowly and…

Representing convex geometries by almost-circles
Gábor Czédli, János Kincses
Finite convex geometries are combinatorial structures. It follows from a recent result of M.\ Richter and L.G.\ Rogers that there is an infinite set of planar convex polyg…

Swing lattice game and a short proof of the swing lemma for planar semimodular lattices
Gábor Czédli, Géza Makay
The swing lemma, due to G. Grätzer for slim semimodular lattices and extended by G. Czédli and G. Grätzer for all planar semimodular lattices, describes the congruence generated by…
