Realizing an m-Uniform Four-Chromatic Hypergraph with Disks
Gábor Damásdi
I am a mathematician working in combinatorial & discrete geometry. I am currently a postdoctoral researcher at the HUN-REN Alfréd Rényi Institute of Mathematics and a teaching assistant at Eötvös Loránd University. Some of my favourite topics:
- Geometric representations of graphs and hypergraphs
- Coloring geometric graphs and hypergraphs
- Graph drawings
- Arrangements of pseudocircles
- Ramsey theory
- Helly-type theorems
