Learning Outcomes

On successful completion of this module, students will be able to

  • Apply various standard methods (separation of variables, integrating factors, reduction of order, undetermined coefficients) to solve certain types of differential equations (separable, first-order linear, linear with constant coefficients).
  • Give examples of differential equations for which either existence or uniqueness of solutions fails.
  • Compute the exponential of a square matrix.
  • Use either linearization or the Lyapunov theorems to check the stability of critical points for a given autonomous system.

Module Content

  • Terminology (order, scalar vs. system, linear vs. nonlinear, invariant).
  • Separable equations, first-order equations, Gronwall inequality.
  • Existence and uniqueness of solutions, blow up in finite time.
  • First-order linear systems, exponential of a square matrix.
  • Reduction of order, undetermined coefficients, variation of parameters.
  • Autonomous systems, stability theory, Lyapunov functions.
