Syllabus: The wave equation, the heat equation, Laplace's equation, and other classical equations of mathematical physics and their generalizations. Solutions in series of eigenfunctions, maximum principles, the method of characteristics, Green's functions, and discussion of well-posedness problems.

Prerequisites: MTH 164 and 165, or MTH 174.

Textbook: Walter Strauss, Partial Differential Equations: An Introduction 2nd Edition, Wiley 2007.

Grading: Homework 100%.

Homework

Homework is assigned biweekly on Wednesdays, starting 1/31. It is due in two weeks, on Gradescope, every Wednesday. (Except HW5 due 04/27) In order to ensure that assignments are graded promptly, and to discourage students from falling behind, LATE ASSIGNMENTS WILL NOT BE ACCEPTED UNDER ANY CIRCUMSTANCES. However, in recognition of the fact that unavoidable issues sometimes arise, the lowest two homework grades of each student's homework grades (including zeros for unsubmitted assignments) will be dropped when calculating final semester grades. Despite this policy, you should complete every assignment, even if you miss a deadline, because math is accumulative.

Course policies

1. We use absolute grading system. Tentatively, the cut-offs are 80% for A, 75% for B+, 70% for B, 65% for C+, 60% for C, 55% for D+, 50% for D. That is, if everyone gets above 80%, then everyone gets an A.

2. Incomplete "I" grades are almost never given. The only justification is a documented serious medical problem or a genuine personal/family emergency. Falling behind in this course or problems with workload on other courses are not acceptable reasons.

3. You are responsible for knowing and abiding by the University of Rochester's academic integrity code. Any violation of academic integrity will be pursued according to the specified procedures.
