Reminders

Announcements

I've put the proof that a trigonal curve of genus 5
isn't an intersection of quadrics at the end.

I've been asked about the passing cutoff for the course.
I don't have one. However, I'm unlikely to fail anyone
who does a reasonable amount of work.

Please send feedback with suggestions for the class.

Office hours:.
Mike's are T 10-11:30 and T,Th 1-2.
Chun Hong's are W 10-11PM and F 10-11AM.
We use the same zoom meeting as for the class: 590 832 338.

Please sign in during the first half hour.
We may leave if no one is there.
As always, you can email us at any time.
Since I haven't learned how to use piazza,
email may be better.
