I have made a sheet ¡­

I have made a sheet with solutions to the friday exercises on Ark1. They are sketchy, some times only extended hints, but anyhow, I hope they will be useful for you.

I also posted a small note about Perron's theorem, which I talked about a little more than a week ago. It is not part of the curriculum, but made for those of you who are interested.
