Introduction:
The Department of Combinatorics and its Applications was founded in 2021, when the Department of Discrete Mathematics was divided into three smaller groups the sizes of which is closer to that of the other departments of the institute. Although formally we form three different divisions, we organize all three combinatorial seminars of the institute together with the Departmen of Graph Theory and the Department of Extremal Combinatorics:
- Kombinatorika szeminárium (video lectures here),
- Extremális halmazrendszerek szeminárium (video lectures here),
- Kombinatorikus keresés szeminárium (video lectures here).
