For Monday's class:

For Wednesday's class:

Wednesday is the last day of class!
Don't forget to turn in your homework by 12:50!
Watch these videos:
- Six Color Theorem
- Five Color Theorem
- Four Color Theorem
If you need the lecture notes, they are available here.
There was a meeting on Zoom at 12:50, on the Seven (?!) Color Theorem. My notes + the solution to my drawing on a mug. Just imagine the edge between gas and the white house is passing inside the mug (where the coffee normally is), and the edge between electricity and the green house is passing on the handle.
After class, I will post the final exam (for those not doing a final project).
