### Course Structure:

*Textbooks:*
A. Vasy "Partial Differential Equations",
L.C. Evans "Partial Differential Equations",
and Y. Pinchover and J. Rubinstein
"An Introduction to Partial Differential Equations"
Lecture notes, to be more or less continuously updated
There will be one midterm, and a final. Homeworks will be
due on some Thursdays.

### Homeworks:

### Homework 1 (Due Thursday October 5)

Read the notes, Evans 2.1-2.2, and Pinchover-Rubinstein
2.1-2.4 for the method characteristics (but not in every detail, and
only what is relevant for linear equations, we will come back to this
later in the class), 7.1-7.2 for general education, and study 7.3-7.4.
Section 7.5 has Green's identities, as does Appendix C.2 of Evans.
