Graduate Course 22M:313

Functional Analysis

Fall 2006

Some facts and observations:

We will be getting a course email account, a class account, and I will circulate this (with links) and other course material during the semester. Stay tuned!

See also (will be updated)

Course Meeting Schedule:

MWF 3:30 in MLH 205.

Course Books:

The course will start at the beginning, and it will be both pure and applied. We will open with the book by Ron Douglas, and I checked that it is in the bookstores.

Both books for the course are on as well. But the second book (by Jorgensen) will arrive (per drop-shipment) in our bookstore here sooner than at More details on Jorgensen's home page.

Relevant Seminars:

FYI: The two seminars, Operator Theory and Math Physics for fall 2006.

One organizational meeting Tuesday 8/22 at 1:30 in VAN 301 (that's the Physics building!)

Two slots: 1:30, and 2:30.

General course info:

Copies of the Syllabus are placed in the basket outside my office door. We will discuss HW + Exams, and class projects as the course progresses.

What is Functional analysis?

Function spaces, operators in Hilbert space, operator theory/operator algebras, mathematical physics (especially quantum theory), representations of groups, mathematical probability theory.

The answer (to the question "What is Functional analysis?") changes over time, and some answers refer to the mathematical tools, while others to a variety of applications; see e.g., the article by Vershik (handout!)

Topics and names from Vershik's article (P.S. Functional analysis is alive and well!): S. Banach's three theorems: (a) Hahn-Banach (extensions), (b) H. Steinhaus (uniform boundedness), and (c) the inverse mapping theorem (closed graph.)
