After giving consideration to all ¡­

After giving consideration to all incoming messages I have decided to keep the Monday lecture at the scheduled time, namely from 12:15 to 14, with one hour of lecture from 12:15 to 13 and one hour of problems solving from 13:15 to 14. For those who cannot attend one or both of these hours please talk to me (or to other students who attend) about the contents of the material covered.
