- HW6 solutions are available here.
- Homework assignment 6, due on Thursday, April 6, is now posted.
- Next time (March 23), we will start Hilbert spaces. Please see here for more details.
- Midterm 2 solutions are available here.
- Midterm 2 was on Thursday, March 16.
It covered everything from the Hahn-Banach theorem to weak and weak* convergence.
- Solutions to homework assignment 4 are available here. (Update, 03/14:
a student has pointed out that the solution to Q2 was incomplete. This has now been corrected.)
- Office hours schedule change: Office hours on Tuesdays have been moved to 1:30-2:30.
Office hours on Thursdays are still 10-11.
- Midterm 1 solutions are available here.
- Midterm 1 was on Tuesday, February 7, 11-12:30.
The test covered all material done in class up to Jan. 30: Banach spaces, bounded linear operators,
basic function spaces including L^p spaces (see
the summary here). From Section 5.2, you are responsible for
the definition of linear functionals, bounded linear functionals, and dual space, but not yet for
the Hahn-Banach theorem.
- Classroom change: Starting on Tuesday Jan. 10, classes will be held in MATX 1102.
Mathematics 421/510 (Functional Analysis),
Tue Thur 11-12:30, MATX 1102
Instructor: Prof. Laba
Prerequisites: MATH 420/507, or equivalent background in measure theory and real analysis.
Textbook: Gerald B. Folland, Real Analysis: Modern Techniques and Their Applications, 2nd ed.,
John Wiley and Sons, 1999, ISBN 0-471-31716-0
This cross-listed 4th year undergraduate and graduate course
provides an introduction to functional analysis. It will be based on
Chapters 5-8 of the textbook. Most of the emphasis will be on Chapter 5, with the
main topics as follows:
Time permitting, we will also explore the applications of abstract functional analysis
to other areas of mathematics such as harmonic analysis,
mathematical physics and partial differential equations:
- Normed vector spaces, Banach spaces
- Linear operators and linear functionals
- Operator spaces: strong, weak, and weak$^*$ topologies
- Hahn-Banach theorem, open mapping theorem, closed graph theorem
- Hilbert spaces and their geometry
- Operators on Hilbert spaces
We may occasionally encounter topics that are only mentioned briefly, if at all, in the textbook.
In such cases, additional resources will be provided. You may also want to take notes in class.
- Lp spaces
- Radon measures and the Riesz representation theorem
- Fourier series and Fourier analysis
Your course mark will be based on homework (40%)
and two midterm exams (30% each). The grades may be scaled at the end of the course.
There will be no final exam.
There will be two in-class 80-minute midterms, scheduled on Tuesdays, February 7 and March 16
(note the revised date).
Both midterms will be strictly closed-book:
no formula sheets, calculators, or other aids will be allowed.
Homework assignments: Homework
will be assigned on a regular basis, every 1-2 weeks.
Each assignment will be announced and posted here at least a week in advance.
The assignments are due in class on the due date.
If you cannot come to class, you may drop off your homework at your instructor's office
before 11 am on the due date. Late assignments will not be accepted.
Solutions will be posted on the course webpage immediately after the lecture.
To allow for minor illnesses and other emergencies, the lowest homework score will be dropped.
Academic concession: Missing a midterm, or handing in a homework
after the deadline, will result in a mark of 0.
Exceptions may be granted in two cases: prior consent of the
instructor, or a documented medical reason.
Your course mark will then be based on your remaining coursework.

- Mathematics Learning Centre:
The Math Learning Centre (or MLC for short) is a space for undergraduate students to
study math together, with support from tutors, who are graduate and undergraduate
students in the math department.
Please note that while students are encouraged to seek help with homework,
the MLC is not a place to check answers or receive solutions, rather, their aim is
to aid students in becoming better learners and to develop critical thinking in a mathematical setting.
The MLC is
located in Rooms 301 and 302 in the Leonard S. Klinck (LSK)
Building, and is open Monday through Friday, 11:00am to 6:00pm. Check
the website above for any changes to hours and announcements.

located in Math Annex 1119, sells
math exam packages (old exams together with solution sets)
for a nominal price before each final exam session.
