Learning outcomes

In order to pass the course (grade 3) the student should be able to

  • describe the most common partial differential equations that appear in problems concerning e.g. heat conduction, flow, elasticity and wave propagation;
  • give an account of basic questions concerning the existence and uniqueness of solutions, and continuous dependence of initial and boundary data;
  • solve simple first order equations using the method of characteristics;
  • classify second order equations;
  • solve simple initial and boundary value problems using e.g. d'Alembert's solution formula, separation of variables, Fourier series expansion or expansion in other orthogonal systems;
  • describe, compute and analyse wave propagation and heat conduction in mathematical terms;
  • formulate maximum principles for various equations and derive consequences.
