The course will discuss the solution of Boundary Value Problems for classical Partial Differential Equations.

The text that will be used is:

David L. Powers, Boundary Value Problem 6th Edition, Harcourt Academic Press. If you have the fifth edition you can use it. There are only minor differences with the newest edition. Some of the exercises have changed number. Incase one such exercise is assigned has a HW the number relative to the fifth edition will appear in square brakets (e.g. [12]).

There will be two midterm. The first midterm will be on Friday 6/18 and the second on Friday 7/9. The midterms will test all the material covered up to the Friday before the test date.

The exercise listed are for HW collection. I will collect them every two weeks and grade 2 or 3 exercises among the one assigned.

The final greade will be based on the following rules: 50% final, 40% midterms, 10% HW. Curving will be done on the final result.

Assignments for the Long Distance students are due 1 weeks after the normal students due date.
