Solutions for some problems 20.03

I have uploaded videos with solutions of some of the problems for March 20th here:

3.4, 3.7, 3.12, 2.13a (You can also find them on the schedule page)

I will try to upload written solutions for the rest of the problems.

Next week the plan is to do something more interactive via zoom in the usual time slot on Friday 12:15-14:00.
