In this course we received a great overview over quite some mathematical disciplines and fundamental ideas, such as first-order logic, ZF(C), ordinals, cardinals and Kuratowski-Zorn, as well as a bit of graph theory, group theory, an introduction to number theory with a focus on modules and chain breaks and finally potency series. You can find more information and materials here: fundamental structures of mathematics

I am a teaching assistent in linear algebra at the time and regularly publishing materials here: linear algebra
