Lecturer Contact Information

My office is Carslaw room 712 and I will often be available there to answer question. You can also email me with this link to ask questions or make an appointment.

Class Times

The lecture times for the course are Monday and Tuesday 10am-11am in Carslaw 830.

Textbook

Most of the course is close to parts of the lecture notes by A/Prof Daniel Daners ``Introduction to Functional Analysis". I also warmly recommend the new monograph by M. Einsiedler and T. Ward ``Functional Analysis, Spectral Theory, and Applications".

The textbook contains many exercises, some of which will be assigned as homework.

Exercise Sheets

Course Outline

Functional Analysis is one of the major areas of modern mathematics. Roughly speaking it is an infinite-dimensional generalisation of Linear Algebra -- it is studying various properties of linear continuous transformations on normed infinite-dimensional spaces. Functional Analysis plays a fundamental role in such areas as Differential Equations/PDE, Representation Theory, and Probability.

We will cover the following topics:

If time will permit, by use of the Spectral Theory we will prove the Theorem of Peter-Weyl -- every unitary irreducible representation of a compact group is finitely-dimensional.

Each of the above 6 topics has an associated Exercise Sheet, available on the course webpage. We will not have formal tutorials but you should work through the exercises on these sheets.

Background Knowledge

The formal prerequisites are MATH3961 Metric Spaces (Advanced) and MATH3969 Measure Theory and Fourier Analysis (Advanced). You will also need to recall some basic linear algebra in general vector spaces, from MATH2961 Linear Algebra and Vector Calculus (Advanced).

Assessment

30% assignments, 70% exam.

Three assignments each worth 10%, due at the end of weeks 4, 8 and 12, and one closed-book exam worth 70%. Assignment questions will be selected from the Exercise Sheets, and the exam may also contain questions from the Exercise Sheets. These assignments are to be submitted through Turnitin; see the question sheets for further instructions. As usual, you are encouraged to work on exercises with other students, but in a small enough group that everyone can make a contribution, and you should write up your assignment solutions independently.

In the event of special considerations, the maximum possible extension will be 7 days, to allow for assignments and feedback to be returned the following week.

The final exam, worth 70%, will be 2 hours plus 10 minutes reading time, closed-book but with a `formula sheet' provided listing some of the main definitions and formulas from the course. Last year's exam paper will be posted and will be discussed on the Week 13 at a specially organised session. This year's exam will have essentially the same format.
