It covers the following major topics: Fourier series, Fourier transform on R^n, distributions and generalised functions, Sobolev spaces and their applications to partial differential equations. Introduction to singular integrals. PREREQUISITES MA5205 Graduate Analysis I and {MA3266 Introduction to Fourier Analysis or MA3266S Intr.

  3. A Guide to Distribution Theory and Fourier Transforms by Robert S Strichartz, World Scientific, Singapore, 2003. Textbook Available in the Science COOP Bookstore at a significantly reduced student price The use of this textbook is compulsory because you are expected to read ALL of it and work out solutions to most of the problems located at the ends of each of the 8 chapters. If time permits we will supplement the material in this textbook with additional material covering singular integral operators and selected topics in harmonic analysis.

  4. What are Distributions? • The Calculus of Distributions • Fourier Transforms • Fourier Transforms of Tempered Distributions • Solving Partial Differential Equations • The Structure of Distributions • Fourier Analysis • Sobolev Theory and Microlocal Analysis Contents of Textbook My aim to is cover all of the material in about 9 weeks, to spend 1 week for tests, and cover supplementary topics in the remaining weeks

  5. Lets forget about details for now – those WILL come Functions as Operators associate to a function the operator what’s this ? enjoy ? Question What properties does

  6. Very Useful Notation Corollary Proof Wow, that’s deep !

  7. Integration by Parts Definition Lemma Proof to be worked out in class

  8. Heaviside Function Definition Theorem Proof to be worked out in class Definition Notation Definition Lemma

  9. Assignment 1 Read Preface and Chapter 1 Do Problems 1-14 and prepare to solve on the board in class for Friday
