Dear student,
On Monday the 19th there was no lecture. The teacher has no responsibility at all for this delay in delivering the first lecture. As MIM's director, I apologise for not having informed you previously of this unpleasant outcome.
This coming Monday, the 26th, professor André Rocha delivers the lecture, and requests a previous reading that is available at Moodle platform. To make your life easier, I also attach it to this message.
The lectures are in presential mode.
Best wishes.
José.
