Where MATH-4202 counts

Required by 2 programs:

  • MATH 4-YEAR BA/BSc IN MATHEMATICS
  • MATH HONOURS BSc IN MATHEMATICS

Counts toward 2 more as one option among several, not as a course you must take:

  • MATH 3-YEAR BA/BSc IN MATHEMATICS
  • MATH MINOR IN MATHEMATICS

Read from the departments' own calendar pages, where 71 of 141 programs are only partly machine-readable, so treat these as a minimum rather than the full list. Confirm with an academic advisor.

Description

This course is a study of field axioms, finite and infinite fields, integral domains, fraction fields, division rings, abstract rings, polynomial rings, PID's and UFD's, Galois Theory; solvability of cubic and quartic, unsolvability of the quintic and other classical mathematical problems.
