Discussion session: Fridays 10 to 11:50am with Jacob Rooney.
 

The summer bootcamp helps entering graduate students prepare for the Basic Qualifying Exam. The exam covers material in analysis and linear algebra. In this part of the bootcamp we work on the topics in analysis.

Lectures and homework in the class will cover a sampling of key results in topics from the exam syllabus, and many questions from past exams. But we will not be able to cover all the material for the exam, and so this course is not a substitute for studying on your own. You can find the full syllabus for the exam, and suggested textbooks which cover it, on the exam webpage.

There is no grading for the course, but there will be homework assigned each week. You should write down solutions to the assigned homework, and view the assignments as practice for the Basic Exam. If you have any questions about the assignments the TA and I can help during office hours. You should write your solutions down each week before Friday. The homework will not be graded or marked, but the TA will present solutions to some of the exercises and you can use the discussion on Friday to check that your solutions are correct.

The homework assignments are posted below. Many of the questions are taken from old exams. These are listed as XYY.N, where X indicates the term of the exam (Fall, Winter, or Spring), YY indicates the year, and N is the question number (taken from the analysis part of the exam in the rare case that the linear algebra and analysis parts are numbered separately). The exams are posted online here. Some homework questions will come from the books Analysis I and II by Tao, 3rd edition. These are listed as B.C.S.E where B is the book (either I or II), C is the chapter number, S is the section number, and E is the exercise number.
