The General Exam is a written exam that must be passed before starting work on your dissertation. You should take the general exam as soon as you are ready.
Except in unusual circumstances you should have taken the exam by the time you have completed thirty graduate credits toward your Ph.D. degree or within one year after first enrolling in the graduate program at Stevens,
whichever occurs later. The general exam is offered twice a year, usually during the third week of January and the third week of September. Any student who wishes to take the exam during either the winter or the fall session must communicate his or her intention at least a month in advance to the Department's Administrative Assistant.
The exact date and room will be announced three weeks before the examination. One failure of the General Exam is allowed. A second failure,
however, will result in the student being dropped from the
Ph.D. Program. At this point, he/she can still obtain a Master's
degree, upon completion of the required course work.
The exam consists of two parts taken during the same day. The first part is from 9:00am to 12:00pm and will consist of about six problems similar to the type of questions that appear on final exams of the required courses. The second part of the exam is from 2:00pm to 4:00pm and consists of about four questions covering the same subject areas as the first part of the examination. However, the solutions to the problems may involve a little more "ingenuity" and the ability to see connections between the different subject areas.
The test will cover three subjects: Analysis, Complex Variable and
Algebra.
The courses needed to prepare for the general examination are: Ma 547, 548, 605, 606, 635, 636, 681 or their equivalent.
You can find a description of these courses in the course catalog and the semester when they are regularly offered
here.
Preparation for this examination include reviewing topics in advanced calculus, linear algebra, algebra (without Galois theory), real and complex analysis. The purpose of the exam is to ensure that the student is well-versed on fundamental subjects in mathematics before moving on to research
work.
For each of the three subjects, the following are topics that might appear
on the general examination. Textbook suggestions are also given. At the end some sample exam questions are attached.
Analysis
Elements of set theory, Zorn's lemma, well-ordering, the real number
system, elements of topology, metric spaces, Hausdorff spaces,
compactness, limits, continuity, uniform continuity, the
Bolzano-Weierstrass theorem, derivatives and differentials, mean value
