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, 1st-order linear, linear with constant coefficients;
  • Give examples of differential equations for which either existence or uniqueness of solution fails;
  • Compute the exponential of a square matrix;
  • Apply standard methods (linearization, Lyapunov theorems) to check the stability of critical points for automous systems
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 matrix;
  • Reduction of order, undetermined coefficients, variation of parameters;
  • Autonomous systems, phase portraits, stability, Lyapunov functions.
Module Prerequisite
Introduction to Set Theory and General Topology (MA1126)
Assessment Detail
This module will be examined in a 2 hour examination in Trinity term. Continuous assessment will contribute 20% to the final grade for the module at the annual examination session. Supplemental exams if required will consist of 100% exam.
