# Ph.D. Degree Requirements

Ph.D. candidates must complete a minimum of *36 credits (12 courses)* of graduate mathematics at the 500 level (excluding Math 500, 510-519, 599, 600, seminars, and directed study). These may include graduate courses taken for the M.S. degree.

* ***Note**: Students with prior graduate work at another university must take at least 18 credits (6 courses) of these courses at the University of Idaho.

The Graduate Catalog requires a minimum of 78 credits beyond the Bachelor of Science degree; however, that number can include Math 500, 599, 600, seminars, and directed study, as well as 400 level math courses and some supporting courses from outside mathematics.

## Preliminary Examinations

Three preliminary exams must be passed. These cover:

*Algebra*(555 and 557)*Analysis*(535, and one of 531, 536)

and one exam from one of the following three areas:

*Topology*(521 and 528)*Combinatorics*(two of 575, 576, 579)*Differential Equations*(539, 540)*Functional Analysis*(571, 572)

Course descriptions can be found in the online course catalog.

Students are **strongly encouraged** to make their first attempt at the preliminary examinations by the end of their second year. All three preliminary exams **should typically** be passed no later than the end of the fourth year of graduate study (including years at other universities). The three exams need not all be passed at once. Students will have a total of 3 attempts to pass the three preliminary exams, no matter how many they attempt each time

Prelims will usually be given according to the following schedule:

- Beginning the second full week of classes of the fall semester.
- Beginning the third week prior to finals week of the spring semester.

Preliminary exams are at a significantly higher level than M.S. exams.

When there is a choice of courses covered on a preliminary exam, the student may choose which two courses the exam will cover. Note that course work in the listed courses is not generally adequate preparation for preliminary exams. Each exam is written and is 4.5 hours in length. The following list of texts indicates the coverage on the different exams. Students should be prepared for questions covering any topic in the given texts.

## Reading List for Preliminary Exams

## Dissertation

The dissertation should contain original research and constitute a significant contribution to knowledge in the student’s field of study. Acceptability of the dissertation is to be determined by the student’s major professor and Ph.D. committee.
