Partial Differential Equations (PDEs) are in the heart of applied mathematics and many other scientific disciplines. The course aims at developing understanding about fundamental concepts of PDEs theory, identification and classification of their different types, how they arise in applications, and analytical methods for solving them. Special emphasis would be on wave, heat and Laplace equations.

Learning Outcomes

After the completion of the course, students will be able to

  1. Classify partial differential equations and transform them into canonical form.
  2. Solve linear partial differential equations of both first and second order.
  3. Apply partial derivative equation techniques to predict the behavior of certain phenomena.
  4. Solve partial differential equations by Laplace and Fourier Transform.
