Curriculum of the First Year CoursesAll Ph.D. students are required to take (or place out of) these 600-level courses, although it is possible to take the 500-level courses first if this seems appropriate. In addition, all Ph.D. students are required to take a year of algebraic topology, Math 618/619. Below are descriptions of Math 602/603, 608/609, and 600/601. See the full list of course descriptions for information about other courses.
