Course Meeting Times
Lectures: 2 sessions / week, 1.5 hours / session
18.06 Linear Algebra, 18.700 Linear Algebra, or 18.701 Algebra I; and 18.100A Introduction to Analysis, 18.100B Analysis I, 18.100P Real Analysis, or 18.100Q Real Analysis; or permission of the instructor.
Functional analysis helps to solve problems where the vector space is no longer finite-dimensional, a situation that arises very naturally in many concrete problems. Topics will include:
- normed spaces,
- Hahn-Banach theorem,
- Lebesgue measure,
- measurable functions,
- completeness of Lp spaces,
- Hilbert space,
- compact and self-adjoint operators, as well as
- the spectral theorem.
Textbooks and Notes
There is no assigned textbook for this course. Instead, we will follow lecture notes written by Professor Richard Melrose when he taught the course in 2020, as well as lecture notes taken by an MIT student who took the class with Dr. Rodriguez in 2021.
These can be found in the Lecture Notes and Readings section.
The written homework is extremely important (mathematics is not a spectator sport). The best way to test your knowledge of a concept is to try and use it; this is why you work problems. Collaboration with other students in the class is encouraged, but separate solutions must be written up and collaborators documented at the top right-hand corner of all submitted work. In general, late homework will not be accepted. However, circumstances may arise that warrant an extension; such an extension request should be emailed to the instructor. The lowest individual homework grade will be dropped when computing the final homework grade for the course.
Midterm and Final Assignment
The midterm exam is a 24-hour take-home exam taking place in week 7. The final assignment will be a 48-hour assignment at the end of the course, which looks and smells like an exam but is not one due to technical considerations.
Final letter grade cutoffs will be less than or equal to the “standard cutoffs,” e.g. 90 for A, 80 for B, etc.
