Mathematical Economics

On our first TA session we went through two sets of exercises on some elementary notions of metric spaces, also covered during the lectures. In particular we tried to firmly embed and understand the properties of metric functions and open (closed) balls in metric spaces.

You can find here and here solutions to all the exercises that we saw during the TA session. As mentioned in class, the rest of the exercises are either similar to those we solved or will not preoccupy as in general.

As was spotted during the TA session, the solution to exercise 8 of the first problem set was erroneous. Additionally, the discussion on exercise 12 fell short of a proper answer. In the solutions linked above you can find better answers to both. We will rectify those shortcomings in the next TA session.
