Mathematics 421/510 (Functional Analysis)
Instructor: Professor I. Laba (Math Bldg 200, 604-822-4457,
Lectures: Tue Thur 11-12:30, MATH 202
Office hours: Tue 12:30-2, Thur 10-11, and by appointment.
This course will provide an introduction to functional analysis, with
some applications to other areas of mathematics such as harmonic analysis,
mathematical physics and partial differential equations. The topics will
include the following:
A tentative list of current and upcoming topics
is posted here. (I have added more details on the requisite background
in measure and integration theory.) It will be updated as needed. We will mostly follow
the presentation in Lax's textbook, which I find more user-friendly, but
Conway's book is also a good reference.
