This is a course that I followed for some self-study. I originally found Math 154 (Harvard Mathematics Courses, Course Webpage) on the previous courses of Curtis McMullen while looking into available math55 material. The last time he taught it was in 1997, but LUCKILY he taught again just in time, so I could have a more up-to-date rendition.
The following lists the homeworks that are currently being worked.
