Math 2303: Graduate Analysis 3
MWF 2:00 - 2:50pm -- Thackeray 524
Homework 1 , Homework 2
, Midterm and solutions.
- Instructor. Dr. Marta Lewicka (office hours in Thack
408, Monday, Wednesday 3:00-4:00pm)
- Prerequisites. This is the 3rd course in the Graduate Analysis sequel, directed at
students who have taken 2301 Analysis 1; so that knowledge of Lebesgue
measure and integration, Lebesgue spaces L^p and basic knowledge of
Sobolev spaces W^{1,p} is assumed.
The analysis and linear algebra material in the Math Preliminary Exams syllabus is also assumed.
- Textbooks. The course will be self-contained.
If in doubt, consult with the books:
- Brezis: Functional analysis, Sobolev spaces and Partial
Differential Equations (also, you may read the shorter French
edition: Analyse fonctionelle - Theorie et applications)
- Lieb and Loss: Analysis
- Evans and Gariepy: Measure Theory and Fine Properties of Functions
- Ambrosio, Fusco and Pallara: Functions of Bounded Variation
and Free Discontinuity Problems
- Grades. Grades will be based on one midterm (25%),
homeworks (25%) and a presentation (50%).
Incompletes and make-up exams will almost never be given,
and only for cases of extreme personal tragedy.
- Topics. In addition to the standard theorems below the course will touch upon some
more recent subjects in the Mathematical Analysis.
