Lecture Notes updated (with solutions)

I have updated the lecture notes with some suggested solutions from Monday. In particular, I fixed Exercise 4.25 so that it makes full sense. I have also provided a thorough solution of Exercise 2.2 to amend the little mess at the beginning of the exercise. In any case, try to solve the exercises on your own with your own thoughts and writings.

Please, let me know if there is anything you miss or need. Tomorrow, there will be an extra session of exercise solving.

Best regards,

David
