Ph.D. Preliminary Exams

The preliminary exams, or "prelims," are the examinations required by the department for admission to official candidacy for the Ph.D. degree. Old prelims are available on-line.

Exam Dates

In 2017, the prelims will be offered September 11-14, 9:30am-1:30pm:

  • Algebra: Monday, September 11
  • Real Analysis: Tuesday, September 12
  • Complex Analysis: Wednesday, September 13
  • Manifolds: Thursday, September 14

Exam Process

These exams, four hours in length, are offered every September in the mathematical subjects treated by the designated core courses: algebra, real analysis, complex analysis, and topology and geometry of manifolds.

A student may substitute completion of a full three-quarter sequence of a designated core course, in which grades of 3.8 or above are received each quarter, for the passing of the corresponding preliminary exam. Only one exam can be replaced in this manner.

The written preliminary exams are given once a year, during the week in September that precedes the start of Autumn Quarter by two weeks. Each exam is four hours long, starting at 9:30 a.m. The exams are written and graded by a committee, which gives the results to the Graduate Program Committee. The Graduate Program Committee meets during the week after exams to make decisions about student performances; all students receive notes describing their performances by the end of that week.

The prelims are intended to serve as an objective measure of a student's mastery of basic graduate level mathematics. A student is expected to pass two of the four exams, with at least one pass in either algebra or manifolds, by the September beginning the student's second year in the Ph.D. program. A student who fails to do so will be advised to discontinue studies.

Normally, students take several exams in September of year two, but students are welcome to attempt exams in September of year one. There is no limit on the number of times a student may attempt a given exam.

Exam Topics

There are four exams:

  • Algebra: Topics at the level of 402-3-4 and 504-5-6.
  • Real Analysis: Topics at the level of 424-5-6 and 524-5-6.
  • Complex Analysis: Topics at the level of 534-5-6.
  • Manifolds: Topics at the level of 544-5-6.

Each syllabus below lists certain topics that have appeared on the exams. This list is advisory only – it is intended to suggest the level of the exams, not to prescribe exactly the material that will appear. Past exams can be a useful source of practice questions, but a student need not master all material that has been covered on these exams. A student who knows the material in the syllabus and who has spent some time solving problems should do well on the exams.

Algebra

Topics: Linear algebra (canonical forms for matrices, bilinear forms, spectral theorems), commutative rings (PIDs, UFDs, modules over PIDs, prime and maximal ideals, noetherian rings, Hilbert basis theorem), groups (solvability and simplicity, composition series, Sylow theorems, group actions, permutation groups, and linear groups), fields (roots of polynomials, finite and algebraic extensions, algebraic closure, splitting fields and normal extensions, Galois groups and Galois correspondence, solvability of equations).
