Learning outcomes
Partial differential equations (PDEs) are used to model physical phenomena involving continua, such as fluid dynamics, electromagnetic fields, acoustics, gravitation, and quantum mechanics. They also arise as mathematical models of phenomena involving multivariate functions, for example in mathematical finance. After studying this course, the student is able to derive the basic linear PDEs (transport, heat/diffusion, wave, Laplace) and explain how they model physical phenomena. He/she can prove and apply theorems about solution properties, can solve simple PDE problems using standard analytical solution methods (separation of variables, Dirichlet's principle, Green's functions), and is acquainted with numerical PDE solution packages in Matlab and Maple.
