Course Information

Schedule: MWF 12:30 - 1:20pm in MATH211

Instructor: Arshak Petrosyan
Office Hours: MWF 10:30 -11:30am, or by appointment, in MATH610

Textbook:
[FJ] F. G. Friedlander and M. Joshi, Introduction to the Theory of Distributions, Cambridge University Press, 2nd edition.

Prerequisite: MA544 and a knowledge of linear algebra

Course Description:
The theory of distributions is an extension of classical analysis dealing with the most general notion of differentiability. It is of particular importance in partial differential equations (PDEs) and has applications in virtually every field of modern analysis. This is an introductory course where we will study the basic properties of distributions, convolutions and Fourier transforms, Sobolev spaces, as well as applications to PDEs.

Homework: There is going to be a homework assignment due every other Friday. Assignments will be posted on this page.

Exams: We will have a (take home) midterm exam as well as a final.
