Required Text: Partial Differential Equations: An Introduction. Walter A. Strauss. 2nd Edition (2007).Wiley (978-0470054567)
Prerequisites: MAT102H5, 232H5/233H5, 212H5/242H5.
This course introduces a range of mathematical concepts and techniques in the theory of partial differential equations.
Emphasis will be on specific equations and methods for solving them, rather than on general theory. Most of the course will be
devoted to studying the wave equation, diffusion equation and Laplace's equation. We will learn to pose and solve meaningful
boundary value and initial value problems for these types of equations and we will get acquainted with the basics of Fourier
analysis. By the end of the course students can expect to have a working understanding of the three main PDEs and techniques.
Students are expected to have a solid background in calculus, including all aspects of multivariable calculus. Familiarity with
basic linear algebra and ordinary differential equations is also required, but not as important. In particular students should

Professor: Tuesday, December 18, 10-12. Location: DV2068B
Grading. Grades will be based on eight homework asignments (5% each), Midterm test (25%), and Final exam (35%). I will also occasionally assign bonus problems.
Late work. Extensions for homework deadlines will be considered only for medical reasons. Late assignments will lose 10% per day.Special consideration for late assignments or missed exams must be submitted via e-mail within a week of the original due date. There will be no make-up midterm tests or final. Justifiable absences must be declared on ROSI, undocumented absences will result in zero credit.
