The Mathematics Major

Math majors must take a total of 10 courses in mathematics or related departments (see below) numbered 222 or above. Vector Analysis and Linear Algebra (either 222-250, 225-250, or 230a-230b) are required although exceptionally well-prepared students can sometimes place out of them with DUS approval. Each Mathematics Major must take the senior seminar, Math 480a or b. One section of Math 480 each year is especially designed for Mathematics-Economics majors.

The remaining requirement for the Bachelor of Arts consists of 7 elective courses selected from the 5 categories below. At least two courses must be selected from three of the five categories. Brief descriptions of their contents and structure may be found in the current edition of the Yale College Program of Studies. Some substitutions are possible and may be made with the concurrence of the DUS.

Majors (beginning with the class of 2012) are required to take courses from at least two of the three core areas: Algebra (Math 350 or higher), Real Analysis (Math 300 or 301 or higher) and Complex Analysis (Math 310 or higher). These courses form the core of the undergraduate major. Their companion second semesters, Math 370, 305, and 315, are also highly recommended.

The requirements for the Degree of Bachelor of Science in Mathematics include those for the B.A. degree, plus two additional advanced science courses approved by the DUS.

Algebra, Combinatorics, and Number Theory

Math 350a and Math 370b are often taken as a 2-term sequence. Math 380a and 381b may also be taken for graduate credit, as well as Math 500a and 501b.
