Material for Preliminary Exam A - Analysis Section



The following list gives topics on which the Preliminary Examination A in Analysis will be based. Math 5307 covers many, but not necessarily all, of these topics. Students (even those who have taken Math 5307) are advised to prepare for the examination using many resources, including (but not limited to) the books suggested below.


The number of lectures per section is only a recommendation and is based on 1 hour 20 minute lecture time. The exact amount of time spent on each topic will be decided by the instructor.
