Great lectures and content. I really enjoyed it. However, the solutions exercises could be clearer and in more detail. Thank you!

This course is very well put together. The lectures are very clear and cover a wide range of interesting topics in combinatorics.

Aus der Unterrichtseinheit
A nonlinear recurrence: many faces of Catalan numbers
In this lecture we introduce Catalan numbers and discuss several ways to define them: via triangulations of a polygon, Dyck paths and binary trees. We also prove an explicit formula for Catalan numbers.
