Course Announcement MATH 655 Partial Differential Equations I Fall 2016
Instructor: P. Sacks, 436 Carver firstname.lastname@example.org Office Hours: MF 2-3, TR 11-12
Class meeting time/place: TR 9:30-10:45, 031 Ross Hall
Textbook: Partial Differential Equations, 2nd ed. by L. C. Evans
Prerequisites: MATH 515 or MATH 519 or consent of the instructor
Course description: Introduction to the theory of partial differential equations at the advanced graduate level. The principal concerns are existence, uniqueness and regularity of solutions, methods for representation of solutions and interesting qualitative properties.
I. Study of model linear problems
a. Transport equation
b. Laplace equation
c. Heat equation
d. Wave equation
II. Nonlinear first order equations
a. Method of characteristics
b. Scalar conservation laws
III. Special methods
a. Separation of variables
b. ODE methods – plane wave, travelling wave and similarity solutions
c. Integral transform methods
d. Useful changes of variable
IV. General theory of linear PDEs of arbitrary order
a. Fundamental solutions
b. Local solvability – Malgrange-Ehrenpreis and Cauchy-Kowalewski theorems, Lewy example
d. Wave front sets
Items I-III correspond roughly to Chapters 1-4 in the text. MATH 656, the Spring 2017 continuation of the course, will cover material from Chapters 5-9, specifically Sobolev spaces, general theory of linear elliptic, parabolic and hyperbolic PDEs of second order, and introduction to techniques for the study of nonlinear PDEs.
The course grade will be based on 6-7 homework assignments. Click here for homework assignments.
