These are some older links containing a short description of the particular areas together with links and short, occasionally informal descriptions of my papers related to it. Some papers could appear in more than one category, each time with the appropriate connection emphasized. I don't maintain very much these pages anymore.

- Algebra in Combinatorics
- Combinatorial Optimization
- (Extremal) (Hyper)Graph Theory
- Positional Games
- Pseudorandom Graphs
- Random Structures and Algorithms
- Topology in Combinatorics
