Partial differential equations (PDEs) play critical roles in wide areas of mathematics, science and engineering. This is an introductory course for PDEs, which is accessible to undergraduate and graduate students in mathematics and other scientific disciplines (for example, engineering, physics, and finance) who have completed the prerequisites. The course covers linear partial differential equations, including Poisson, wave and diffusion problems. The focus will be on learning analytic tools to solve these problems. This course does not cover numerical methods for PDEs.

This course is offered in the fall term, and is cross-listed as Math 126 Topics in Applied Mathematics II.
